Problem with response.redirect sending incorrect HTTPMethod

Question

Hi, I've got a strange problem with a Response.Redirect. I'm using VB.NET with the .NET 2 framework (so VS2005 & SP1).

I've got a page that I do a form submit on (that's a proper form method="POST" hard-coded onto the page) and that properly posts me back the page data which is then processed. As part of that processing the system determines if we need to get sent to another URL after processing has been complete. So the request.httpmethod = "POST".

So if the "GotoPage" parameter has a URL specified we then do a response.redirect(URL, false). (False as we want page processing to complete in order to write some timing logs etc).

The page correctly redirects but instead of the response having a "GET" as the request.httpmethod it has a "POST" instead !

Now, we're using our own custom framework so that we use the HTTPRequest method to determine if a page has been posted back or is being "Getted" so the "IsPagePostBack" property doesn't work (that only works when you're using the normal .NET controls and form submissions). In all other instances our code works happily but what might be causing the Request.httpMethod to not be being set correctly ? I've tried doing a response.clear before the redirect in case headers are being written out before hand but to no avail.

Any clues ?!

thanks, Andy

How about trying to clear headers and then adding the one you want? I think "GET" is 304?

response.clearheaders
response.appendheader("GET", 304)
response.redirect(...)
