[Code]....
It works grate on my PC running XP and IIS 5.1
but on my webserver running IIS7 and WS 2008 dosn't works.
I'm using an autocomplete contol of ajax toolkit. Yesterday a user found that it had stopped working (it wasn't generating the list as you type letters in the textbox). After hours of troubleshooting, I found that in web.config <httpHandlers>, this line
<remove verb="*" path="*.asmx" /> was placed after the <add> line like this: <httpHandlers> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
I have a problem with large respones and IIS7, the server runs out of memory. I've written the test code below that works pretty much like my real code... When i start to download the file i can se the memory usage rise until it hits 100% and Firefox complaints about lost connection to server, looks like IIS7 does not release cache or something.. Works in IIS6 by the way
This seems as good a place as any for this question. It has to do with an .ASHX handler.
I have written a generic file serving handler in asp.net/vb.net - it has been working great. I recently moved to a windows 7 box and am now debugging under IIS7, and this is where the problems occure.
Whenever I serve a file to either FireFox or Chrome (IE8 works fine) from IIS 7, the download will fail.
- In FireFox the error is "[some file name and path].part could not be saved, because the source file could not be read." - In Chrome the error is "Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error." - In IE8 it works fine
If I run the same code in IIS6, it works fine. If I run the same code in the Visual Studio virtual web server, it works fine (on windows 7 or XP).
I am rather concerned about this as our production web server will soon be IIS7; which I'm starting to really love, and would hate to revert to IIS6 just because this won't work in IIS7.
Here is the code I'm using..I've tried a number of different patterns. It seems to always fail on the Flush() line with the error "System.Web.HttpException = {"The remote host closed the connection. The error code is 0x80070040."}"
One thing I have noticed, if I move the flush statment to the finally clause or remove it all together; firefox will attempt to read the entire file - it appears to be looping through the entire block of code just fine, until it hits the flush statement. If I remove the flush statment I still get an error and it still tries to read the entire file before asking me to save it.
--Edit: I removed the flush and tested again; firfox thinks it downloaded a zero byte file.
I'm assuming I just have some sort of header issue going on here, but I'm at a loss at this point as to what that would be.
In IIS6 the scenario below is working perfectly.I have an HttpModule called URLRedirect which examines URLS and by using RegEx rewrites of applicable. An example is a URL "/doc47.pdf" gets redirected to docpdf.ashx?id=47 Then the docpdf.ashx used the id value and, using a database builds an application/pdf document and returns it. Since I need to validate that the user has access to the data, the first line of the ProcessRequest(HttpContext context) function is:if (context.User.Identity.IsAuthenticated) ..... This is where the problem occurs, but more details first.
On a webpage, access to which is restricted to lgged on users who meet certain criteria there is a link which allows the user to present the page as a PDF document. This is achieved by using javascript to open a popup window using the window.open("/doc47.pdf", ... ) function.This all works fine under IIS6 and under IIS7 if I change the mode to Classic. But, under IIS7 in integrated mode, the following happens.The line in doc.ashx described above raises an exception because context.User == null. But, and this is interesting, if instead of using the link that opens the popup window I instead type /doc.pdf?id=47 into the address bar, the PDF document displays correctly.So this indicates to me that the URLRedirect Module is somehow losing the logged on user information.
am trying to write an HttpModule that will work in IIS7 with integrated pipeline mode AppPool. Within this module I need to access Session variables and to be able to capture the Session Start and End events. I have found a couple of articles on this topic that indicate the need to modify the behavior of the HttpHandler in PostAcquireRequestState to force the Session for the context to be initialized. The article I am using as a template is posted here:[URL]In my case I am getting the following error:
[NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616
I believe that this error implies a problem with attempting to attach an event handler multiple times. I am aware that the modules Init function can be called more than once and have set a static initialization flag which ensures that I will only ever attach the event handler once.In the most condensed form my code is as follows:
public class HttpModule : IHttpModule, IRequiresSessionState
Our website used to be a php website, now everything changed to .net, but the customer still want to keep the original php Request url. I want to know How to set Handler mapping on IIS7 to redirect .php file to .aspx file ? In more details, when you click handler mappings on IIS 7.0, what kind of hanlder should you add (add managed handler or add script map or add wild card script map or add module mapping) to redirect .php file to .aspx file?
I recently started learning about HttpModules and made my first one. I was wondering if someone could explain why some modules in the the web.config include a lot of extra info and others do not.
I have...a dynamic populated select box several input boxes a submit button form fields are loaded initially using cookies several dynamic populated divs
I want... start loading the content of my DIVs after all FORM elements have been loaded completely (= filled with data, select boxes are populated)
I attempted to find any information in regards to best practices of handling errors inside of a HttpModule unfortunately I can't seem to find any information on Google in regards to this.
All the information I've found all pertains in how to use the global.asax or a custom http module to log errors which is completely not pertinent.
Edit: Clearly this question has been misunderstood. I am seeking information regarding software patterns that are employed to prevent a HttpModules from faulting, triggering custom errors redirection, and faulting again causing infinite exception chains until IIS shuts down the thread entirely.
This however is very nontrivial since the HttpSessionState collection can't be depended on for the life cycle of HttpModules. Since error conditions have already occurred it would be improper to expect that I could read the ASP.NET session cookie to get an identifier that I could store user specific data in the application cache. Storing data in the HttpRequest.Items collection would be pointless since that in no way exists across multiple requests.
i have found out a way to find controls on content pages by using
var txt = $('input[id$=TextBox1]'). But how to access html elements like "<p>" tag and others in jquery when the html elements are in content page only.

As I am working thru the NerdDinner MVC example. I found that after implementing step 6 that edits to a dinner were no longer saved. After some investigation I found that I needed to add the ValueProvider to the UpdateModel function call in Edit (HttpPost) example. My updated code is below.
I'm trying to enable rewrited urls in my project.it's very good described in this post: urlrewriting by scottgu It works very well when im running it on localhost, but as soon as i upload it to my host (.net 3.5), it doesn't work! i always get redirected to a 404 page!Is there a configuration needed to enable this? as scottgu says no, but i don't find out why it's not working.
On the website I am working on it has been deployed but the problem I am facing is that when I enter a username and password and click on the check box to remember...It remembers the password for sometime.. wen I login in after 5 or 10 minutes it remembers the password but aftr a long period of time like about 2hours it forgets the username and password and i have to type it in all over again... this dint used to happen with the old server as even I could sign in and it remembered the password the next day until i log off... what can be the reason
I have an ASP.NET 4 site that uses the new SQL CE 4 CTP. The site works fine locally (IIS 7.5 on Win7) and fine in Server 2003/IIS 6. It fails when deploying to IIS 7 on Server 2008. The error I get is:
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
The interesting thing is if I switch the app pool user from its default user to LocalSystem, everything works great. So clearly there is a permissions problem somewhere.
Long story short, does anyone know what special permissions need to be set when deploying a SQL CE 4 database? (BTW, we have already set r/w access on the db itself and on c:windows emp)
I have an app with 7 tabpanels with lot of content so my application is very slow. I wish to load the content of the panels when they are clicked, not before. How do I do that? My app consists of user controls
