I am working on a c# .NET website in which the user can click on a link and get redirected to another web page in a separate website also owned by us. The code is very easy to understand, there is a switch followed by a call to Response.Redirect(the_url_we_want_to_go_to).
I have debugged it numerous times and I can confirm that when the debugger hits this redirect line that the parameter is correct. It points to the QA version of this other website. qa.samplesite.com lets say. However, the browser does not go there. The browser instead hits the test environment instead. Lets call it test.samplesite.com. This is the problem.
I understand there are a million things in between the app servers these two separate websites are on, but maybe one of you has seen something like this before. More specifically, is there a way to catch outbound traffic in the debugger or is there a way to see outbound traffic on the app server itself (in IIS)? I am familiar with intercepting inbound traffic inside of httpmodules. Maybe this isnt a stackoverflow question...
Thanks for your help!
Use the very nice HTTP sniffer "Fiddler". It will allow you to see all HTTP requests. You should verfiy that a) the redirect target is correct (it might be overwritten later in the request pipeline. A Response.Redirect is not the final word) and b) that you don't have a second redirect after the first one.
