AJAX :: Request Takes A Few Minutes Then Times Out - Only In Firefox
Nov 22, 2010
I have a very peculiar problem that I've been wrapping my head around and I just can't figure it out. I have an updatepanel. Inside that I have a TabContainer. And inside that I have three TabPanels, each of which has checkboxes. Sometimes (and it happens often enough that I can easily reproduce it, but strangely may not happen with the same exact steps), when I click on different tabs or click on checkboxes inside the tabpanels (basically when I do an AJAX async postback), the request takes about a few minutes, after which the request just stops. Looking at the Firefox error console, I see this popping up after a few minutes...
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0 Now, the asyncpostbacktimeout property for the ToolkitScriptManager is set at 360000, which is 6000 minutes, so the problem has nothing to do with that setting. In IE, I never have this problem and the AJAX requests are instantaneous and smooth, no delays. So this isn't a network or database lag issue. Something to do with how AJAX is run in Firefox. Why is it that sometimes, an AJAX request in Firefox takes a few minutes and just stops processing the request? And once again, the steps to reproduce this problem may not be the same every time, it seems random - very strange. Google searches have yielded very little help on this. I've tried things like extending the timeout property (which again has nothing to do with this), setting Response.Cache.SetNoStore() everywhere. Is there a crude workaround I can do (at this point, I'm willing to settle for a workaround). I just don't know anymore.

My basic structure is that I have a table on a page, which I want to reload without refreshing the entire page. So on clicking a button on the page it fires of this:
function RefreshMissionsAjax() {
//fade out the old table.
$(clientID('MissionsDisplay')).fadeOut(500);
//request the new value from the page (calls the GetIncompleteMissions() method in the MissionViewer.aspx.cs page)
$.ajax({
type: "POST",
url: "MissionViewer.aspx/GetIncompleteMissions",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
$(clientID('MissionsDisplay')).html(msg.d);
$(clientID('MissionsDisplay')).fadeIn(500);
},
error: function (xhr, ajaxOptions, thrownError) {
$(clientID('MissionsDisplay')).html('An error occured while trying to refresh the page data.');
$(clientID('MissionsDisplay')).fadeIn(500);
}
});
}
And I have in the code bedind of an aspx page:
[WebMethod]
public static string GetIncompleteMissions()
{
return GetHTMLTable();
}
This method just grabs some data, and creates a html table - nothing too fancy. When the returned table is small (a dozen rows or less) then it works like a charm. But when it gets larger, it takes a long long time. At 100 rows it can take 5 minutes to render the table. At 1000 rows I have left it for 30 minutes and nothing will happen after the fadeout. (NB - it loads fairly quickly on the pageload, before the ajax refresh is used, so it is not the actual server side creation of the table thats the problem).
This is my first real attempt at doing something like this, so I dont know if this is the best way to do it - it was just something i pieced together that worked great when i was testing with small datasets. Now, not so much.

I have a web application which has rather a lot of controls. I also have several buttons (add, edit, save, cancel). Most of my content page is in an update panel so it does not process the whole page. On form submit I have some javascript code which shows a div 50% opacity and an animated gif to prevent users clicking on the buttons more than once whilst it is processing the data to the server. Here is the javascript / call:
Code:
onsubmit="overlay();"
function overlay() {
el = document.getElementById('overlay');
el.style.display = "inline";
document.getElementById('Image2').src = "../Images/loader.gif";
}
function removeoverlay() {
el = document.getElementById('overlay');
el.style.display = "none";
}
The problem is it the form disables like I want it and the giff animates for about 1.5 seconds but it does not enable the form for a further 4 seconds.
Is there anyway to see what it happpening at this point. If I put some watches in my code behind it runs through less than a second so what else can it be doing.
Also on some laptops the form does not fit vertically so there is a scroll bar. When the div is shown on a submit it does not do the full screen including the scroll area.

am querying an Oracle database thru an ASP.NET web page, but the other day, the webpage didn't show any results after 5 minutes which normally takes about 3 secs. Then, 3 hours after, I got an email from the IT Dept asking me to kill my task which was taking a lot of ressources, but I couldn't since there is no way to send a user cancel request as I can do for instance with SQL Naviguator. So, they had to kill it for me. However, I do't want it to happen again because I don't want to overload the servers because of a query that didn't execute properly.
So, I thought about including connection timeout into my connection string, but there is already a default value. So, is it possible to avoid that kind of situation?My code contains a try {} finally {} to trap errors, but I didn't seem to work in this case.

We have an ASP.Net web service the call to which, due to some bad design, often takes more than 20 minutes to return. We have changed every setting that we can think of, but no matter what we do, we always get a timeout after 20 minutes. It happens that this web service is a BizTalk orchestration exposed as a web service, but I do not think that is relevant -- the error is an ASP.Net error.
There must be some setting we can change to increase the timeout to more than 20 minutes, but we've exhausted our knowledge. What setting are we missing? EDIT: Among other setting, we have tried those detailed here: [URL], which includes httpRuntime executionTimeout, sessionState timeout and app pool idle timeout.

I use ASP.NET Ajax in my web site and I am monitoring the HTTP requests per each page. I am surprised by the excessive call of ScriptResource.axd with different query string variables. I am pasting a sample of HTTP trace below. The call for ScriptResource.axd take lots time percentage out of total response time. Is this by design or there is something wrong with my AJAX configuration in web.config?
[Code]....
Actually it is degrading the performance of the application. And the user experience becoming very poor in case of lower bandwidth.

I have been working on a .NET/C# form that contains two time fields that are built out of dropdowns. Time A is made up of two dropdowns for Hours and Minutes and Time B is made up of two drop downs for hours and minutes too. I need to compare the two in order to ensure that Time A is always greater than B. I could just use a CompareValidator to check the hours, that works BUT doesn't take into account the minutes. So lets assume the following scenarios:
A = 11:00 B = 12:15 is fine my validation accepts this as it should do
A = 11:15 B = 11:00 is accepted because the hours are equal but otherwise shouldn't pass as the minutes aren't validated
How would you ensure B is always equal to or greater than A where dropdowns are used? I would if I could change this but not permitted to do so.

I have a site that is using Forms Auth. The client does not want the site session to expire at all for users. In the login page codebehind, the following code is used:
// user passed validation
FormsAuthentication.Initialize();
// grab the user's roles out of the database
String strRole = AssignRoles(UserName.Text);
// creates forms auth ticket with expiration date of 100 years from now and make it persistent
FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1,
UserName.Text, DateTime.Now,
DateTime.Now.AddYears(100), true, strRole,
FormsAuthentication.FormsCookiePath);
// create a cookie and throw the ticket in there, set expiration date to 100 years from now
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,
FormsAuthentication.Encrypt(fat)) { Expires = DateTime.Now.AddYears(100) };
// add the cookie to the response queue
Response.Cookies.Add(cookie);
Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false));
The web.config file auth section looks like this:
<authentication mode="Forms">
<forms name="APLOnlineCompliance" loginUrl="~/Login.aspx" defaultUrl="~/Course/CourseViewer.aspx" />
</authentication>
When I log into the site I do see the cookie correctly being sent to the browser and passed back up: However, when I walk away for 20 minutes or so, come back and try to do anything on the site, the login window reappears. This solution was working for a while on our servers - now it's back. The problem doesn't occur on my local dev box running Cassini in VS2008.

when I access any page of my ASP.NET MVC website first time, then this first request is slow. It needs about 4-5 seconds to load. But every following request to any page is fast.When I wait some minutes or a hour then every first request is slow again. Every following request is fast.
I think that IIS 7 is compiling the code and keep it in memory. After some time it will delete it from memory so it needs to compile it again.What can I do that every first request is as fast as every following request?
(Without precompiling my source, if possible)

I have a web page that performs searching, on very large database about millions and millions of records. The request for this has been sent from an update panel. We know that for this request, the server needs around 1hr to do such a search. And our client even accepts that the server might take such a long time. Till the request is of less than 30 minutes, our search result grid is updated on browser. But if the request is of more than 30mins the update progress keeps on rotating. There is no server timeout of either session, database, iis or the asynchronous post back, that we have defined in script manager.
I have verified my whole web.config and also the machine.config file for any default setting of 30 but haven't got any. Update progress bar keeps rotating for request more than 30 minutes.

A class in my ASP.NET website needs to access a database table multiple times for every request. The database table should rarely change, if ever. Maybe a couple times a month.
In the static constructor of the class, the table is fetched from the DB and cached in a static local variable. Whenever the class needs to access the table, then, it just uses the cached, static version.
My question concerns the lifespan of this cached, static version of the table.
I understand that it's fetched the first time the class is instantiated or a static method in the class is used. But how often does this occur on the web server? What if the table changes and we want to reset this static version of the table?
Basically, I'm wondering, is this table fetched once and then only refetched each time I restart IIS? What, with regard to the site and IIS, will trigger this static class to reset, causing the static table to be refetched?

I implemented a custom IFilterProvider derived from FilterAttributeFilterProvider and
registered it using a Unity based dependency resolver. (Pretty much as described on
Brad Wilson's blog.) While debugging, I noticed that IFilterProvider.GetFilters on my
custom class get called a lot. I counted 4 times per request.
Is this normal or am I doing something wrong?
I have a simple project that reproduces the behavior if anyone is interested.

I have a .NET 3.5 web application that uses SQL Server for its session state store. To improve scalability I wrote a class that implements IPartitionResolver that figures out which instance of SQL Server to use for a users session. All of this works great
and just as expected.
However, when I was debugging one day I set a breakpoint at the bottom of the ResolvePartition method to make sure the correct connection string was being returned. To my surprise this breakpoint was hit many (~5-10) times per request! The same is true about breakpoints in the IPartitionResolver.Initialize method.
Does anyone know why this is? It seems to me that you would only need to call these methods once per request. It's not like the users session is going to move to a different instance of SQL Server mid request.

I want to redirect the user after 2 mins if there is inactivity for 2 mins. I am not using ASP.NEt membership. And I dont want to use Sessiontimeout for this. Session timeout will logout the user even if he is working on the system. My objective is like screensaver process.
If there is no action for the specified time, the screensaver runs. Similarly, I want to redirect the user to login page.
note that i have already handled it with the following javascript:
[Code]....
Here what my problem is,
the user is working on the site...ok.. he want to see someother site.he browse someother site and works on....or even he can do some other work in his system...but he is active in his system... What this script does is, it automatically logout the user and redirect him to login page. But it should not do while he is active...IT SHOULD REDIRECT IF HE IS NOT ACTIVE REALLY (Similar to Screensaver process)
Is it possible ?

I've recently enabled Digest Authentication on an intranet website/application I am creating for my company in ASP.NET.
The reason I have done so is because Windows Authentication seemed to only work for some users, and not for others. I could not figure out why nor do I know enough about IIS to try and trace the issue. After some trial and error, I found that digest authentication seemed to give me the behaviour that I wanted. That is: allow only users with a valid account on the domain to log in to the website with their credentials.
The problem now, is that Firefox (3+) seems to ask for the user to authenticate on every HTTP request sent to the server. This does not appear to occur in Internet Explorer (6+) or Chrome.
I've tried searching for solutions but I always arrive at dead-ends. I'll find a discussion about the issue, and every posted solution leads to a dead link...or it's on Experts Exchange and I don't have access to view to solution.
The issue appears to be related (from what I've read) to the way the different browsers send their authentication headers vs how IIS interprets them. I'm not sure what I can do to change this though? One of the solutions I had found mentioned writing an ISAPI filter to fix this, but of course the link to the finished filter was broken and I have no idea how to go about making one myself.
I've tried messing with the NTLM and other auth related strings in about:config to try and force Firefox to trust my server but that doesn't seem to work either.
From a few other sources I've read, it appears that everything should work if I switch back to Windows Authentication, but then I'm back at square one where the authentication would work only for some users and not others.
A solution for either problem would work for me, but I have very little information for the Windows Authentication issue. If someone could guide me through tracing the problem I'd gladly post more information for it as well.

I have a need to show sensative information but I would only like it available on screen for 2 minutes, and then after it dissapears.
Since this is part of my web application, I would like the user to stay logged into the web site before and after viewing the information, but in order to view it, I would like them to re-enter their username/password.
Are there any directions I can be pointed into accomplish this task?

I implemented a chat using the COMET "way" described in this article: http://www.codeproject.com/KB/aspnet/CometAsync.aspx
In this example, the client connects for 5 seconds every time. I wanted to hold the client longer, for about 10 minutes.
My problem is - how to detect if the client disconnected during those 10 minutes? I tried using Response.IsClientConnected but it returns true even if I close the client. There must by some inidicator since the socket gets disconnected if I close the client.

I'm try to get my site to detect what browser someone is using to ensure they're using one that is compliant with our site. Everything works, except Firefox seems to post the wrong version in the Request.Browser variables.I'm on Firefox 3.6.10, but Request.Browser shows Mozilla 1.9.2.10. It's correct in the HTTP_USER_AGENT string:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 YFF35 Firefox/3.6.10 ( .NET CLR 3.5.30729)
Is there a way to detect it better without having to parse through the HTTP_USER_AGENT string?
