[squid-users] Dynamic content

[Jiri Wetter]

Hello,

I have problem with caching of dynamic content.

I verified conditions which have to be met in order to cache dynamic content here: http://wiki.squid-cache.org/SquidFaq/InnerWorkings#How_come_some_objects_do_not_get_cached.3F
and also check by online tool  https://redbot.org/
Result is that my page can be cached but it doesn't work with my current settings. Therefore I would like to ask you for help with my configuration.

OS: Ubuntu 12.04.5 LTS
Squid Cache: Version 3.1.19
configure options:  '--build=x86_64-linux-gnu' '--prefix=/usr' '--includedir=${prefix}/include' '--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' '--sysconfdir=/etc' '--localstatedir=/var' '--libexecdir=${prefix}/lib/squid3' '--srcdir=.'
