The following Internet Explorer error occurs when POSTing a form to an Active Server Pages (.asp) file that initiates multiple "response.redirect."
The conditions that cause this error to occur are as follows:
- The requesting page uses a Post to an ASP page.
- The ASP page issues a "Response.redirect" ("HTTP302").
- The redirected page redirects to another page.
The correct solution is to re-design the Web application so that a redirect is not issued when a HTM forms submits a POST.
This bug was corrected in Windows 2000.
The following text is from the HTTP 1.0 Specificiation located on:
9.3 Redirection 3xx
302 Moved Temporarily
If the 302 status code is received in response to a request using the POST method, the user agent must not automatically redirect the request unless it can be confirmed by the user since this might change the conditions under which the request was issued.
NOTE: When automatically redirecting a POST request after receiving a 302 status code, some existing user agents will erroneously change it into a GET request.
Internet Explorer incorrectly handles the situation described above in that it erroneously changes it into a GET request when it should fail or prompt the user to confirm the redirect.
