Preamble: the problem happens only when using firefox under the LAN of my company. My company guarantees all functins working with IE but doesn't with Firefox.

For security reasons we must browse using a proxy server, placed somewhere in France, which (according to what I understood from SysAd), is composed by different physical machines that change randomically every few seconds.

When visiting a page requiring a login, after sending the password through a form, every few seconds Firefox detects that the IP of the page I'm visiting chaged and pops up with the message (sorry I'm translating it back from firefox italian version, I'm not sure about the actual message in english)
"This page is about to be readdressed to a new destination. Would you like to send again data of the form to the new address?"

Under this condition, Firefox becomes almost unusable!
It would be nice to have the possibility to disable this message, or have a flag for a default answer.

Reproducible: Always

Steps to Reproduce:
1. login in facebook or any other site requiring user name and PW to enter
Actual Results:  
every few seconds, the pop-up message appears and you have to click on "OK" to go on.

Expected Results:  
Would be nice to have a flag like "take always this answer from now on"

Doing the same things at home, both with direct connection or under a public proxy server, the problem does not appear.

The text (RepostFormData, "This web page is being redirected to a new location. Would you like to resend the form data you have typed to the new location?") is send due to bug 48202. It's a temporary redirect (http response code 307).
