HTTPHandler : IRequiresSessionState Halts Execution Of Pages?
Jul 22, 2010
I have ASHX HTTPHandler which implements IRequiresSessionState. When I call this handler, and call aspx page of same application in another window, aspx page does not start processing until ashx page finishes processing. Even call to same ashx page from two different windows show that page which gets called first executes and then the next one.When I do not implement IRequiresSessionState, pages load asynchronously without waiting for other page to complete.

MSDN got a page showing in which order ASP.Net global.asax methods are invoked. I can't seem to find it, anyone got a linkAre there a similar page, but for ASP.Net MVC (including in which order all controller methods are invoked like OnActionExecuting, OnAuthorization etc)?

I have an MVC2 application, and HttpHandler Library. The library, to simplify, serves an image. The problem is that if I invoke this handler from the root page ( http://whatever/ ), everything works fine. If, however, I change the Global.asax, so the same page now has the address of http://whatever/controller/action - it doesn't work (ALT text comes out instead of image).I didn't write the handler library, but I have the code; so I put a breakpoint in ProcessRequest function of IHttpHandler implementation. For good situation the breakpoint gets triggered, but for bad case it isn't. So, I assume that the handler isn't invoked for non-root pages.

I have a website that's in Classic ASP on a hosted server. I'd like to be able to create some "virtual" pages so I can specify google-friendly URLs that translate to ASPs [URL] this_is_the_help_page instead of [URL]admin/helpsubsystem/help.aspx?current_user etc As the server also supports ASP.NET - could I use an HTTP Handler to intercept these calls and do any necessary translations?

I have a handler, like this, using IRequiresSessionState:
public class MyHandler : IHttpHandler, IRequiresSessionState
{
// code
}
In the code, I am able to read and set Session values. I also check ensure that the caller is logged in. That all works fine.
The web site uses forms authentication, so in the web.config, I have this:
<authentication mode="Forms">
<forms loginUrl="Login.aspx" timeout="10" slidingExpiration="true"></forms>
</authentication>
The problem is that AJAX calls from the client to the server code MyHandler do not extend the life of the session!
So even if the user is busy sending and receiving data from the server, they time out 10 minutes after their last full page load.
In the handler, I've tried specifically changing a value is the session on each call, but not even that extends the time out.

In an ASP.NET application, I need to do some changes on every CSS file sent.So I created an HttpHandler (inside the app itself), added:
<add verb="*" path="*.css" type="MyWebsite.CssTestHandler,MyWebsite"/>
to Web.config in system.web/httpHandlers and modified the handler like this:
public void ProcessRequest(HttpContext context)
{
context.Response.Clear();
text.Response.Write("Hello World");
context.Response.End();
}

I heard that DataReader works on forward only readonly fashion and at a time it willread a single record.Suppose when i execute the below code
SqlDataReader reader=cmd.ExecuteReader();
gv1.DataSource=reader;
gv.DataBind();
How the does the gridview populate all records?.As the reader is capable of reading one row per read,I thought only the last row is available for GridView to display.

I have created a HttpHandler to be used with SWFUpload to upload images to the server. This upload is done in an administration backend so users need to be authenticated to upload images.Initially I made the whole administration area deny annonymous users but because of the way SWFUpload appears to work it wouldn't work correctly with Forms authentication and would return a 302 status code.I had thought it would be possible to make the location of my handler public in Web.config and use context.User.Identity.IsAuthenticated in my handler to determine if the user is logged in.

How can I tell from within an ASP.NET HttpHandler if it is executing because of a call to Server.Execute("myHandler.ashx")or because of the user linking directly to myHandler.ashx? (Besides using a querystring parameter).

I am recording time taken by a page to be displayed to user, for which I am recording execution end time in page_PreRender. But if the page contains huge amount of data, then it is taking few more seconds after PreRender event. I also tried with Page_Unload, still the same.

I have a query:
Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12)
When I am executing this query, it is taking 1-2 seconds to execute, but when I am using the same query in stored procedure, the below query is taking more than 5 minute:
If(Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12))
BEGIN
-- CREATE TEMPORARY TABLE [Say: #temp1]
#temp1 => Select a from tbl_abc where id in ( select id from tbl_xyz where mainid = 12)
inserting the same value in the temp table
drop #temp1
END
what could be the reason of this? and how can I resolve this? I am running the SP from asp.net

My task is to create an ASP.NET application with a piece of code which will automatically run every half an hour. This code must append a record to the file every half an hour. It should not depend on users requests(whether they happen or not).
1) I'm writing my code in Application.Start method of Global.asax file. Am I right?
2) Do I have anything to do with the hosting (IIS) settings (e.g. change permissions to write the file, etc)?
I have already tried just putting the code to write to file into a loop in Application.Start method and then just copied the project directory to the server. However, it didn't work.

I would like to check how long an ASP.NET page takes to execute (server stuff obviously, not interested in how long it takes to throw the results down the line and for the browser to render them at this stage).
Having done some searching, I came across http:[URL] which shows how to do just this. Trouble is, it doesn't work for me. I copied the code exactly, but the execution time is always zero.
I tried enabling tracing, and that showed an elapsed time between Page_Init and Page_PreRender, but the values returned by Environment.TickCount were exactly the same in both events, so the elapsed time was 9obviously) zero.
