AltostratusIE obeying - sometimes?
I've got an iRule that is supposed to redirect the browser to a new URL to ensure that the user is using "www" as a subdomain. Quite basic stuff. Works great in Firefox, but it's hit and miss in IE (e...

Did that (used Wireshark). Redirects are coming back fine, although there's a checksum error. However, upon continually requesting the same URL eventually IE will follow the redirect - even though the checksum error still exists.
I did find a Microsoft bulletin about IE 4.x running into this problem if the redirect is split between frames. Haven't examined the frames yet.

Since the response is coming back I assume that all is well. Need to convince the Sys Admin to give me console access...

Tried that - no difference. Used HTTP::response, HTTP:redirect, with and without quotation marks, varied the response codes, etc. No difference.
However: I found that the problem is not limited to IE. Turns out that Firefox doesn't simply give up when it encounters the "host not found" error - it will retry with the subdomain "www". This masks the problem in FF.
In the meantime, I started suspecting that other iRules might be interfering. Apparently (can you confirm?) the Big-IP does not stop processing iRules when it encounters a redirect - if there are other iRules those will still be processed.
Adding "event disable all" right after the redirect seemed to have fixed at least this problem.
