[squid-users] Issue with Citrix sessions and squid

[David Touzeau]

Thanks Yuri,

Any tips how to increase TCP/IP stack ?
Did you means TCP/IP stack on the Citrix Server side or on the squid 
box  or both ?

Because , all computers that did not use Citrix can surf trough squid 
and open unlimited tabs without any issue.
And Citrix sessions that *did not use Squid* can surf trough Internet 
and open unlimited tabs without any issue.
