advance ........

as noticing php sessions , varnish not intermix nicely, ie phpsessions destroys cachebility of urls within varnish makes them unique.

options: 1. disable php sessions altogether (doubt thats real option you). 2. enable php sessions on pages absolutely need it, rest can cached. 3. split session-related php logic separate php files , include using esi main pages. allow partially cache pages (the non-esi bits).
