I was testing out my custom error handling specifically around 404s when I came across an intersting problem, which I recreated on a new web application.
Create web application
Create a global.asax file
Create a new web form - error.aspx - "This is the error page text"

I have a web service hosted on a web server, I invoke the web service using jquery ajax.
The service returns results successfully when invoked locally from the server, but it fails when invoked from a remote client machine (not in the same domain).
I see the request fail in the firebug returning error (401 UnAuthorized) and the response has the following error (Request format is unrecognized for URL unexpectedly ending in '/List').
I am trying to use the Application_Error to redirect the user to a custom error page. I know I could use the web.config to do this, but let's assume for now that this is not a desirable path to take.
Initially, I tried to do a Response.Redirect to perform this, however, there seem to be occasions where the current http context does not define the response object. So, I attempted to perform a check to make sure that the response object is not null prior to attempting the redirection, and if it is not defined, perform a Server.Transfer instead.
What happens is that in most cases, the Redirect causes the browser to some generic "friendlyish" error page rather than the requested error page.
So then I tried using Server.Transfer exclusively, and this worked well for most cases, however, sometimes the transfer didn't seem to take in the browser. Changing it back to a redirect in these cases solved that problem, but reintroduced the issue where the errors previously being captured and transferred now were being redirected.
What I surmised from this is that in certain contexts where the Application_Error method is trapped, it is necessary to use Server.Transfer in redirection, whereas in others, it is necessary to use Response.Redirect. The question then became twofold: (a) When is one necessary and when is the other? and (b) What available information can I poll to tell me when a given condition exists.
After much searching, I cannot find a reasonable answer to this question. So I began to trap errors and examine the HttpContext object for some indicator. One thing that I was looking for is the reason why if even with a defined Response in the current context does a redirect fail. The only thing that stood out is that even though a Response object may exist, the Session data could be absent. I added the case to check whether the Session data was null and perform a Transfer in this case and it
seems to be handling it properly.
I emphasize "seems to be handling it properly" because no documentation I've been able to find confirms either the problem I am having or whether this is an appropriate strategy for solving it.
I guess the question is, am I on the right track here or is the null Session object just a red herring, indicative of nothing relevant. Here's the check I have set up for reference.

I have writen error handling code in my Application_Error event in global.aspx page, but that event is not executed any time when error is occurring.So do I need to take care any other settings on my application to run this.
View 2 RepliesI am handling errors in Global.asax. When I encounter an error in certain pages, the Application_Error event fires twice. On the second trip, Server.GetLastError() returns null. I have a simple page where I throw an error in page load. When that page throws an error the code below works fine. I also have a more complex page with an update panel and many controls. When that page throws an error Application_Error fires twice. I suspect the update panel but update panels are always suspect, right?
There are no try/catch blocks on any of my pages I'm testing with. Custom errors in web.config is commented out. Note that logging and busywork in the Application_Error event are commented out. I'm pretty much just doing a respone.redirect. The problem with the the event firing twice is that the response.redirect fails with an error msg stating that headers have already been sent (adding Context.ClearError and Response.Clear does nothing to fix that).
I have an application written in VB.NET that sends XML to another server and it takes another XML. I am using HttpWebRequest in sending it but when I get the request stream I got this error. Please note that the application is working on my machine, but on the deployment on server I got this error.

Is there a simple way to fix elements in a html document that miss the ending tag, or /> ending? I'm using ASP.NET with c# (loads html with the help of Html Agility Pack).
An example:
<img src="www.example.com/image.jpg">
should transform into
<img src="www.example.com/image.jpg" />
or
<img src="www.example.com/image.jpg"></img>
I have a login which of coarse sets a session. session("User") = "Yes" if that session is "Yes" then ....they are logged in. But. I can for the life of me, determine why the session is ending on its own....at no specific time. Once you do a few thing on the site ....it ends....and never at the same time...it could be 1 minute. it could be 10... Are there any Alternatives to using session state. Many people have looked at my code and found NOTHING wrong at all.
View 8 RepliesI have an inline .asmx file that I'm trying to host on GoDaddy. Because of this, I cannot edit the web.config file :(. Either way, I can access [URL] When I try this, I see the service description page that ASP.NET generates. However, when I try to access the method, I receive the "Request format is unrecognized for URL unexpectedly ending" error.
I have not changed the .asmx from what Visual Studio generates. I'm simply trying to access [URL] as described here: [URL]
My question is, is there a way that I can host .asmx files on GoDaddy? From my Googling (or Binging) it seems that I need to edit the web.config file to be able to run this service.

How to find an element Starting and Ending with certain text using Jquery? For example:
<div
id="AAxxxxZZ"> AAxxxxZZ
</div>
<div
id="BxxxxU"> BxxxxU
</div>
<div
id="CxxxxY"> CxxxxY
</div>
if I need to find an element with id that starts with AA and end with ZZ
As part of a CMS, I have created a custom VirtualPathProvider which is designed to serve a single file in place of an actual file structure. I have it set up such that if a file actually exists on the server, that file will be served. If the file does not exist, the virtual content stored for that address will be served instead. This is similar to the concept of serving a website from files stored in a database, though in this case the content is stored in XML files on the server.
This setup works perfectly when a request is made to a specific page. For example, if I ask for "www.mysite.com/foobar.aspx", the content that is stored for "foobar.aspx" will be served. Further, if I ask for "www.mysite.com/subdir/foobar.aspx", the appropriate content will also be served.
The problem is this: If I ask for something like "www.mysite.com/foobar", things begin to fall apart. If the directory exists on disk (and doesn't have a configured default page in IIS, such as index.aspx), I will get a "Directory Listing Denied" error. If the directory does not exist, I'll simply get a 404 - Resource Not Found.
I've tried several things, and so far nothing I've done has made a bit of difference. It seems as though IIS is simply noting the nonexistence of a directory (or default file in an existing directory) and serving up its own error code, without ever asking my application what to do with the request. If it ever did get to the application, I would be able to solve the problem, but as it stands, I'm quite lost. Does anyone know if there is some setting in IIS that is causing this?
I've looked for every resource I can find on the subject, and am coming up empty. I know this should be possible, because I have read tutorials on serving content from both databases and ZIP files.
p.s., I am running IIS6 and .NET 3.5
I just released a new version of my web application on ASP.NET V4.0 (on IIS 7 Win2008 R2) For some reason, the application Restarts at (almost) every request. I cannot figure out what configuration (although I didn't change it) or code error may cause this problem. Mind this happens on a hosted server - so I have a somewhat limited ability to debug it.

View 1 RepliesI am working with three machines. The printer is shared and it is attached to one machine. Second machine contains published pages and on third machine I am developing the application. I have an application which uses combit's list & label for label printing. I am able to print label from the project. Means while debugging the project, printing works fine without any problem(from the development machine). But when I deploy(publish) this project in IIS by making virtual directory and then try to run, it does not work(on deployment machine). The browser freezes and does not show any error as well. After closing browser and running the same page takes a lot of time just to load the page.(not even shows the complete GUI, just white page...) Eventually I have to restart the IIS. Does anybody have idea regarding this?
