Re: An IE bug and HAproxy?

Hello Joe,

I run into a similar problem, when using haproxy version greater 1.3.16 in conjunction with ssl (stunnel). After a post no data was sent back to IE. Using firefox everything is fine.

I also noticed that the order of the entries on the statistic's page changed with the new versions.

> Hi. I have a problem with a possible IE bug and HAproxy: every now and then when submitting a form (using POST method) IE's status line shows "Waiting for https://...." and after the predefined period (60 s in the servers configuration file) the server terminates the connection. This happens daily approximately to 1 % of users and usually rebooting the user's computer normalizes the situation. This has happened also to my own IE using the server via HAproxy over LAN, _BUT_ never so far when the browser accesses the server directly. So despite the fact that rebooting the IE machine helps the situation and so IE is the root of the problem, it has something to do with HAproxy also.

But recently I noticed that if I make HAproxy's timeouts shorter than the server's timeout, IE waits the amount of time defined in HAproxy's 'timeout server' and after that the page is submitted. For example the following configuration

> timeout connect 5000

> timeout client 10000

> timeout server 10000
