IIS Response Not Reaching Back To Client
Oct 12, 2010
I got a strange issue after hosting the my site in IIS 7.5, Windows server 2008 64 bit
The applicaion is created in ASP.Net 2.0
The page with issue has following workflow:
Upload a file from browser (may be very large size ~50 MB)Perform some process (May take very long time: up to 30 minuits)Notifies the client that process is done.During the process client uses something like http://www.codeproject.com/KB/session/Session_Defibrillator.aspx to keep the session alive.
The Issue:
The client does not get any response sent by my code after the process is over. It should refresh the page with the response provided by my code. But instead it only shows waiting for... in the status bar.
I have tried this on IE and firefox.
To veryfy the process is over
I have added some trance message in my code to check when the process gets finished.I have also checked the Log from IIS, it also shows that response sent with Code 200.
Please help me solving this issue:
What could be the issue?How can I diagnose and fix this problem?In what cases connection between browser and IIS server gets lost.

is there a way in c# to be able to ping a url every 15 minutes and get a response back from the server?
i want to try to see if .net can be used to build a simple tool to have asp.net websites invoke a re-build so that the first user doesn't incur the load penalty when the application is started.

Does a response.Redirect first postback to the page that's calling the redirect before actually redirecting? I don't think so but my debugging is showing me that it is.
I can see it doing so and that causes me a problem. The problem is this:
1) My page has an asp.net button on it
2) When the button is clicked, the page posts back of course. Then the following is called in the event handler method for that button:
Response.Redirect("Checkout?frpp=1"), true);
3) But I notice that when the redirect is called, it first goes back and hits the page load for this page, the page that's doing the redirecting. Well that is causing me problems because it's calling code that I don't want it to be calling again such as this:
if (!IsPostBackl)
ShowOrderItems();
so it's like I'm doing a 2nd postback:
first postback happens when you click the button, hits the event handler, runs my handler method which calls the Redirect. Redirect is called but it's doing another postback to the same page here..why?

I have a webservice that sends the response back in XML format.I'm able to connect and call the webservice adding an external web reference to the Visual Studio project.Then in my code behind:As New servicename_addedLabel1.Text = servicename_added.Functionexposed(param1, param2, etc)With that code I can get the response in a large label and unstructured data. If I "view source" I see the XML structured data.I have tried to create an XML document without success.My goal is to parse the response and write it to a database separating all the fields.

My web site is integrated into a client web site. Client web site reaches out to my site through an Xml request and I return Html embedded in an Xml response. Client site then displays the Html in an area on a page on their site. All is well so far...
Now, there is a link on the Html that does an HttpPost back to my site which causes a re-direct to another page on my site. i.e. [URL] -> HttpPost -> [URL]-> Response.Redirect("CookieTest.aspx"). Still, all is well. [URL]
All of the above can occur without authentication to mysite. Where I start running into problems is when CookieTest wants to do a FormsAuthentication.SetAuthCookie(). If I put a button on CookieTest that does FormsAuthentication.SetAuthCookie() and then Response.Redirect("SecurePage.aspx"), still under [URL], the SecurePage does not recognize the authentication because the auth cookie is not present.
1. Navigate straight to CookieTest.aspx
So I simplfied the problem into basic cookie set/read excercise and used the code below to test out cookie writing/reading ability. When I call the page directly from the browser I see that on initial load the response cookies are empty. Then on button click I see that the cookie is properly set in the response. Then on subsequent page refresh I see that the page load shows the request cookie.
2. Navigate to CookieTest.aspx in an HttpPost from [URL], as mentioned above.
Now on button click I see the cookie in the Response but do not see it come back in the Request of subsequent page refreshes, as if the client browser is rejecting cookies set by my server.
3. Navigate straight to CookieTest.aspx, then do the HttpPost from [URL]
In this case, since the cookie was set during a straight navigation to CookieTest.aspx, the cookie is present in the subsequent HttpPost/Redirect from [URL]. CookieTest.aspx has full access to the cookie and can even delete it.
4. Have CookieTest.aspx pop a new browser window simply sets the cookie and closes itself down.
Similar to #3, if the cookie is set through a popup window and then CookieTest is refreshed the cookie is present in the Request.
Notes:
The code does prove that the client browser accepts cookies.
When my page (CookieTest.aspx) is shown within the frame on the [URl] page, during any link back to my server, the Request.Url.Host shows my domain.

I have a button that when clicked, will generate a PDF and write it out to the response.This is the basic structure of the code:
try
{
using(Stream stream = generatePdf())
{
[code]...
Downloading the file works fine, except that it doesn't complete the postback.If I were to throw an exception above file.Transmit, the error handling would work properly and I would see the message get displayed in my browser. However, if there is an exception after the file.Transmit then nothing happens. The user saves/opens the pdf and the page does not reload.How can I make it so that the postback always completes, that way I can display an appropriate message to the user?

What I have?I have a ASP.NET page which allows the user to download file a on a button click. User can select the file he wants from a list of available files (RadioButtonList) and clicks on download button to download it. (I should not provide link for each file that can be downloaded - this is the requirement).What I want?I want the user to download multiple files one by one by selecting the required radio button and clicking on the button.What problem am I facing?I can download the file for the first time properly. But, after downloading, if I select some other file and click on the button to download it, click event of the button does not post back and the second file will not be downloaded.I use the follwoing code on the button click event:
protected void btnDownload_Click(object sender, EventArgs e)
{
string viewXml = exporter.Export();
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=views.cov");
Response.AddHeader("Content-Length", viewXml.Length.ToString());
Response.ContentType = "text/plain";
Response.Write(viewXml);
Response.End();
}

we have windows xp operating system, here we installed my website that will be stored in the location(c://programFiles/) if we run the sample after executing ouputfile(scan.pdf)image file will be stored in C://inetpubs/ftproot/(if file transfer type is FTP). if file transfer type is HTTP then the image file is transfered to the location:c://programFiles/website1/app-data. If we install the same website in windows 2007 64 bit os website will be stored at c://programfile x(86)/. if we run the sample through ftp it is running fine and file is stored at FTP folder. but if we run the same application through HTTP, file is not transferring to destination folder(c://programFiles x(86)/website1/app-data.)

I've been pulling my hair out about this for ages. I have a WebService which sends a zip file to the browser. This works; when I test the WebService and 'invoke' the method through it directly, the zip file is downloaded to the browser correctly.
The problem arises when I use jQuery to send an AJAX request to the WebService - the zip file is downloaded to the response, but it stays in the response and doesn't download as a file.
Here is my code:
[Code]....
Now this works since the file downloads when I use the 'invoke' function when navigating directly to the service.
Here is my jQuery AJAX request...
[Code]....
I added the code in 'beforeSend' so that the request states explicitly what type of response the browser should expect.
I've been using Firebug to monitor the request/response headers and can't see anything wrong with them (except when I look at the content of the response, it's full of binary data AND its the same size as the file I'm sending.
I just attempted to upload screen-dumps of the request/response headers and the content of the reponse but I don't have enough reputation points to do this yet :-(
The Response is the same size of the Zip file so I'm assuming its being sent back to the browser, but the browser doesn't know what to do with it.
Tested in IE, FF & Chrome and the results are consistent.

I create my own litte ViewEngine, done many things that works great, but now I want something to implement, but I don't know how.
I want the final Response Content when the controller is executed and the view is executed, manuelly manipulate and than send to the client.
I have two Examples for it.
First I have an AssetManager, he collects all Css files and JavaScript files, given by components, the view, classes and so on.
And this collected links I will insert with String.indexOf before the "</head" tag.
The reason why I want do this in the engine and not with a line like this in the head part
[Code]....
Is that I want so save me the work to do this every time on each project in the master page and maybe in single views.
A second usefull idea is, I want to write my own litte trace component, and I want so write the generated content before the "</html>" tag.
where I can manipulate the content before sending it to the client, and this in the engine?

I have a page that when the user clicks a button there is a custom loading panel placed in the update panel by the PageRequestManager BeginRequest event. So when the page is loaded the loading panel is removed. My issue is that when the user clicks a button that redirects to an httphandler the page is not reloaded therefore the loading panel is never removed.
So I'm trying to think of a way to remove the loading panel before the redirect occurs, whether this be with a client script call before the redirect or what ever. So far I've thought about trying to do Response.write("..."), then Response.Redirect().

Is it possible to cache the response of a http handler on the server and on the client?This doesn't seem to be doing the trick:
_context.Response.Cache.SetCacheability(HttpCacheability.Public);
_context.Response.Cache.SetExpires(DateTime.Now.AddDays(7));

This question seems to be pretty close to what I am looking for - I was able to setup tracing and I am looking at the log entries for my calls to the service.However I need to see the raw soap request with the data I am sending to the service and I see no way of doing that from the SvcTraceViewer (only log entries are shown but no data sent to the service) - am I just missing configuration?
<system.diagnostics>
<sources>
<source name="System.ServiceModel"
switchValue="Verbose"
propagateActivity="true">

There is an external (Java based ) web service that i am calling. I've added my service reference and verified that Reference.cs has been generated.
Then i call my service form my client website like such:
[Code]....
But my response object is mostly null after it receives the response. The properties that should have values do NOT.
When i look at Trace viewer, the SOAP request is correct and the SOAP response is correct. I get back a valid soap response with all the data i need it's just not making its way back to my response object. I've tried regenerating the proxy many different ways (svcutil) with no luck.
Example of what is in the response object (good data which is not making it's way back to my response object):
<ogc:Spatial_Capabilities><ogc:GeometryOperands><ogc:GeometryOperand>gml:Envelope</ogc:GeometryOperand><ogc:GeometryOperand>gml:Point</ogc:GeometryOperand><ogc:GeometryOperand>gml:LineString</ogc:GeometryOperand><ogc:GeometryOperand>gml:Polygon</ogc:GeometryOperand></ogc:GeometryOperands><ogc:SpatialOperators><ogc:SpatialOperator name="BBOX"></ogc:SpatialOperator><ogc:SpatialOperator name="Overlaps"></ogc:SpatialOperator></ogc:SpatialOperators></ogc:Spatial_Capabilities>
Why isn't the SOAP response making its way back to my response object?

I have a VB.NET ASP.NET webserver program running. One or more VB.NET clients are making use of it. Nothing special so far. As far as I know, the server is not really aware of the clients. Clients can request data. But is it also possible to let the server call-back a specific client when something happens? So that the client doesn't need to poll?
To be more specific, this server is connected with hardware modules. Clients could be terminals that show the status of a sensor for example. When a sensor gives an "alarm" value, it would be nice if the server could pass that alarm towards the clients. Instead of letting the clients to check each X seconds if that alarm is active. Would be a waste of energy, especially because the chance this alarm goes off is almost zero...

I'm converting a bunch of FOXPRO / FOXWEB apps to ASP.NET.
The underlying DB is still foxpro (for the moment).
I am passing a table to some VB.NET code that I want to have converted to a CSV file and sent back to the client for download. And it works! Sort of ... It works sometimes, but at other times, instead of asking me if I want to download the CSV file, it just spews the file to the browser window.
On the asp side, I am passing the response object, the table and the csv file name.

(I think) with using a data bound Custom Control on the server to get hold of my data (it will be part of a larger dataset) and to ultimately pass updates to the database. The bit I'm researching at the moment is passing that data to and from the client.One way to pass the data to the client is to use JSON within the Pageload event to construct a set of Javascript objects (one per row in the data). Is that the best way, or am I missing something?
Then, after the data has been manipulated on the client, I need to pass the rows back again so that the server side code can pick them up and process the updates. I've seen a suggestion on here that a hidden text field is one way to do that. Is it the best?Neither of my approaches seem to be at all elegant - and I suspect that I am missing something fundamental in ASP .NET AJAX!
