AjaxControlToolkit.ToolKitScriptManager.OnInit() throws thread abort exception for every aspx page. I have an asp.net 2.0 Ajax application, where I have set the following properties of ToolScriptManager on my pages.
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnableScriptGlobalization="true"
EnableScriptLocalization="true" CombineScripts="true" EnablePageMethods="true">
<Scripts>
I have this configuration on all the aspx pages in my application. When I checked the .NET CLR exception Performance counter I figured out a large number of exceptions, mainly one exception per page load is occuring. On running windbg I was noticed that
AjaxControlToolkit.ToolKitScriptManager.OnInit() has the following code block which is getting executed. The OutputCombinedScriptFile() returns true. But since I am setting my controls on DesignTime still designmode is set to false for toolkitscriptmanager.
if (!DesignMode && (null != Context) && OutputCombinedScriptFile(Context))
{
// This was a combined script request that was satisfied; end all processing now
Page.Response.End();
}
I am not sure if this is a reported bug or even a bug with ajax, but this is causing havoc in my load test results as I have around 3 hundred thousand HTTP requests to be handled per day out of which 80% are aspx page requests resulting in a large number of threadafbortexceptions, thus affecting the performance.

View 1 RepliesI'm new to threading and have used it successfully, but limited. I can spawn a thread and have the main thread reference variables in the spawned thread, but I don't know how to allow the spawned thread to reference (and update) variables in the main thread.
Any example threading code I've seen on the web appears to be WAY more complicated than what I do, so I am unable to understand or integrate into my code.
Here is a quick example of how I use threading:
[code].....
I am reading the Asp.net security documentation on msdn.I come across these tow terms and get really confused.
# WindowsIdentity = WindowsIdentity.GetCurrent()
which returns the identity of the security context of the currently executing Win32 thread.
# Thread = Thread.CurrentPrincipal
which returns the principal of the currently executing .NET thread which rides on top of the Win32 thread.
I have a password page and when someone enters an incorrect password I want to simply foil a brute force attack by having
bool isGoodPassword = (password == expected_password);
lock (this)
{
if (!isGoodPassword)
Thread.Sleep(2000);
}
I would expect that this would allow all correct passwords without stalling, but if one user enters a bad password another successful password from a different user would also be blocked. However, the lock doesn't seem to lock across ASP.NET threads.
I want a example of multithreading .i want to use it in a web form not on console.i am using C#.net .and how to use thread.sleep method for a particular thread.

I connect to a web address using HttpWebRequest object (http://www.website.com/page1.aspx), this page should redirect me to another page (http://www.website.com/page2.aspx). What I want to do are two things:
Redirect (http://www.website.com/page1.aspx) to (http://www.website.com/page2.aspx) by HttpWebRequest obeject.Get the new URL (http://www.website.com/page2.aspx) from HttpWebResponse.
I tried to post data to client HTTPPost URL, as per the client specification I need to post the data using "Post" method and I used the same. But it throws an error "The remote server returned an error: (500)Internal Server Error". in the HTTpWebResponse.My post URL does not have any specific page like http://abc.com/post/post.aspx. the actual URL looks like "http://abc.com/post", Can we post the lead without any specific page like I said in the above URl?

My response should be a url.I'l getting respStr="http%3A%2F%2..."How can I convert respStr to string in order to create URI url = new URI(respStr); ?
Does a HttpWebResponse.StatusCode detect Asp.Net errors? Mainly a yellow screen of death? Some Background: I am working on a simple c# console app that will test servers and services to make sure they are still functioning properly. I assumed since the HttpStatusCodes are enumerated with OK, Moved, InteralServerError, etc... that I could simply do the following.
WebRequest request = WebRequest.Create(url);
request.Timeout = 10000;
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
if (response == null || response.StatusCode != HttpStatusCode.OK)
{
// SERVER IS OK
return false;
}
else
{
// SERVER HAS SOME PROBLEMS
return true;
}
I found out this morning however that this doesn't work. An ASP.Net application crashed showing a Yellow Screen Of Death and my application didn't seem to mind because the response.StatusCode equaled HttpStatusCode.OK. What am I missing?
HttpWebResponse response;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException webexp)
{
response = (HttpWebResponse)webexp.Response;
}
I'm trying to read a response from an encoded apache server, the post works fine but i'm ripping my hair out over the response, it was working yesterday and they've turned off compression now so there is no contenttype encoding getting passed back.I'm using fiddler and getting this response back for the response type below; i'm basically trying to read a XML into a XmlDocument from the responded string and all i'm geetting back is encoded characters no matter what i do, so can someone please give me a hand with this before i make myself bald before 30.

I have a file, a.pdf, stored on a SharePoint server behind Windows authentication. I want to make a.pdf available through another Web app with forms authentication. Basically, link is clicked and up pops the open / save as dialog for the pdf (or other document file) I've set up my HTTPWebRequest and passed credentials, getting my data into a stream (file.GetResponseStream).
I've tried converting the stream to a byte array and then using response.write or response.output.write with no luck (stream not seekable) I've tried using a streamreader and doing a response.write(streamreader.readtoend()) and response.write(memorystream.toarray(),0,memorystream.toarray().length) with no luck (the message received from the server could not be parsed).
i have managed to get the only table from rediff and its working fine the whole table is showing.
1 .But when i try to see the string by responce.write it show only 1st line not the full table..Why??
2. I want to feed this in my data base so the full table can be stored nad retrived..How?

I need to check whether the request will return a 500 Server Internal Error or not (so getting the error is expected). I'm doing this:
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "GET";
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
if (response.StatusCode == HttpStatusCode.OK)
return true;
else
return false;
But when I get the 500 Internal Server Error, a WebException is thrown, and I don't want to depend on it to control the application flow - how can this be done?
I have the following code (yes it is winforms but the code could obviously just as easily be a webform).
Stream str = null;
MemoryStream ms = null;
FileStream fs = null;

My problem is that although the response length is correct at around 21MB, the stream is returned far too quickly (pretty much instant) and the byte array ends up being filled with only a small number of bytes. The response is clearly not returning the full file so what am I doing wrong?
An external user of a website (it's actually *his* website) is getting a 403 error when he tries to run. He is physically outside our office, but I can run it fine. I was told by our network engineer that it's probably a virtual directory security setting and I can change it in IIS. Does anyone know what he means? We are running IIS7.
View 4 RepliesI have a web application that built on using VS2005 running under an XP operating system. Recently the computer was upgraded to Vista. After installing VS2005 and all pages, pressing the RUN button throws an error where the start page is "forbidden". I have replaced the page with a test page named "Test.asp" that merely says hello, and that does not display (access is forbidden). I haven't a clue. I am an administrator on the machine. Does anyone know what this problem is?
