191586 - Mozilla performs multiple POST submissions on page load timeout or cgi timeout

Status: RESOLVED DUPLICATE of bug 184122

(Core :: Networking: HTTP, defect)

Description

[Thomas Swan]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2.1) Gecko/20021130

Mozilla will perform repeated POST operations on forms if the receiving form
terminates prematurely or Mozilla times out on page retrieval (I have been
unable to determine which case) multiple times until stopped.

Case in point a project I was working on generated a form page with over 500
elements and it had an unusually long resolution time (> 60+ seconds).  Mozilla
would post and either timeout or the script would timeout and end prematurely. 
Mozilla continued to post to the script multiple times without issuing an error.  
The session reported as 10 submissions to the same form by the browser from my
one post operation.

This same thing happened during a large move of message in webmail.  Mozilla
reposted the request and the script returned an error.

Multiple form submissions without a message such as ("The POST operation failed,
or ended do you want to resubmit?" is dangerous. 

Reproducible: Sometimes

Steps to Reproduce:
1. Create a form page that keeps hit information in a session but put large
delays so the script execution time will take more than 60 seconds
2. Post to the form page
3. Mozilla will seem to post indefinitely

Actual Results:  
Mozilla repeatedly submitted the form.

Expected Results:  
Mozilla should have submitted the form only once and displayed the resulting
page or issued an error warning the POST operation had failed.  It should NOT
have attempted to submit the form multiple times.

I'm working on a public script so I can demonstrate this fully.  Also, I can
repeat this most of the time, not the sometimes indicated above.

to http networking.

Note that this all got rewritten recently, so retesting with a current nightly
(or 1.3beta once it's available) would be nice.
