Dear All ,

I am trying to setup a load balancing under webmail on my test servers.  Here is my setup details :--
Total server  are 3 servers.  i.e (  2 backend webmail server and 1 front server )

On one server I have installed haproxy-1.4.15.tar.gz + stunnel-4.41.tar.gz with http:// and https://
Another two servers are installed with squirrelmail  .

my problem:--
==========
1) When I access the webmail by https://webmail.domain.com and compose any email  and click on send button , the page is getting expire and  I am getting log out from webmail.
In Firefox there is no error on browser , where as in internet explorer I am getting below error  with popup window :--



Error Popup :--
============

"do you want to view only the webpage content that was deliver securely.
This webpage contain the content that will not be delivered using the secure HTTPS connection, which could compromise the security of entire webpage."

Where as if I check with http://webmail.domain.com , then the mail compose and send work properly.

Here is the stunnel.conf :--
===================

[root@jayesh ~]# cat /etc/stunnel/stunnel.conf
cert=/opt/ssl/ssl.key/mail_domain_com.crt
key=/opt/ssl/ssl.key/domain.key
setuid=stunnel
setgid=stunnel
pid=/var/run/stunnel/stunnel.pid
output = /var/log/stunnel.log
debug = 7

socket=l:TCP_NODELAY=1
socket=r:TCP_NODELAY=1

[https]
  accept=192.168.30.200:443
  connect=192.168.30.200:81
  TIMEOUTclose = 0
  session = 600
  TIMEOUTbusy = 600
  TIMEOUTclose = 300
  TIMEOUTconnect = 600


I checked by defining the TIMEOUTs but I am not able to figure out why the page is getting expire and I am getting logout ?
There is firewall rule between any servers.

Please suggest me and guide on this issue. I am stuck here.

Regards
Jayesh Shinde
