[TYPO3-dev] caching of tt_news with realurl and pagebrowser (cHash problem?)

[Ernesto Baschny [cron IT]]

Hi Simon,

we have several setups like that and not a problem with it. If it works
without realurl it should also work without realurl.

One thing to consider is that if you use "enableCHashCache=1" (as you
seem to be using), you have to make sure every link is being generated
by typolink (and thus realurl) before hand (as it needs to cache the
reverse lookup from the URL to the relevant cHash).

If you just "type in" some URL and expect it to work, it won't, as the
cHash won't be cached (yet).

Make sure you call a page where there is a link (generated through
typolink) to the second page of your news browser. Check with phpmyadmin
if you see the URL in the tx_realurl_chashcache table! If you don't, the
hit will considered an "invalid cHash" and depending on your setup it
will output the page as if there are no (valid) parameters (thus showing
your first page again).

For a test, try turning off enableCHashCache=0 and see how it works then
(if you get a cHash on *every* link).

Cheers,
Eresto
