[TYPO3-dev] Sessions and the "fe_typo_user" cookie

[Arjen Hoekema]

Goodmorning list,

I was wondering if it is possible to set the "fe_typo_user" cookie 
containing the session id only when there is session data that should be 
persisted.

Right now the cookie is always set and makes it impossible for reverse 
proxies (like Varnish/Apache mod_cache) to cache the page.

I know there are some extensions (cache_info, moc_varnish) that change 
the cookie behaviour, but this only works upon login/logout.

A solution could be to trigger the "setSessionCookie" upon actions that 
actually write something to the session (like "setAndSaveSessionData", 
"storeSessionData").

Is there someone who has a nice/clean/better solution?

Grtz,

Arjen Hoekema

Btw: I found this thread about the session handling in FLOW3 which 
describes the same issue/situation: http://forge.typo3.org/issues/26358
