I suggest the problem just required to allow POST method from LAN and/or
to mail servers. Often this can help.

Thanks for the quick reply. please find the answers below
1. while uploading attachments,it stays idle without any advancement in
attachment progress bar.
2. we have tested on IE,Crome and Firefox with the same result.
3. Major mail services used are i. gmail, 2. mail.bsnl.co.in
4. yes, clients can access internet through proxy servers only, no other
way.
5. squid.conf (all the access lists are separate text files)
acl SSL_ports port 443
acl CONNECT method CONNECT
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost manager
http_access deny manager
http_access allow all exceptionlist
The "all" on the above line is doing nothing. You can remove it to
clarify what this config does.
http_access allow sysadmin_ip sysadmin_time sysadmin_url
http_access deny all blacklist
... same for the "all" on the above line.
http_access allow tv_ip
http_access allow sysadmin_ip whitelist
http_access allow workstation_ip whitelist
http_access allow localhost
http_access deny all
http_port 8080
cache deny all
coredump_dir /var/spool/squid
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern . 0 20% 4320
dns_nameservers ip1 ip2 ip3 8.8.8.8
visible_hostname proxyserver
cache_mgr emailid
max_filedescriptors 4096
6. can be informed later
7. I meant to state that this problem occurs in some machines only, that is
on those machines attachment is not uploaded at all.
Which ones? ie. How does the IP correlate to the tv_ip, sysadmin_ip,
workstation_ip ACLs above?
Any difference with attachment size?
Any difference with how those machines are configured to use the proxy
vs ones that work? (Manual setting? WPAD/PAC auto-configuration?)
Any pattern with the client OS type and version?
or the browser versions?
Exactly what version of squid-3.5.x is being used?
Running on what operating system?
Self-built or a packaged Squid from .. where?
If the above questions do not lead you towards an answer, are you able
to get a packet trace to see where the pause is happening
(client<->squid, or squid<->server), and whether the upload is actually
hung, or just not being reported right by the browser.
