[TYPO3-english] New cache hash calculation class

[François Suter]

Hi all,

In TYPO3 4.7 a new class was introduced for refining cache hashes 
calculations (t3lib_cacheHash). I was trying it out to see if it could 
help in a project where I need to have a variable passed in all requests 
(beyond the usual L for language). This variable must be taken into 
account for the cache hash calculation as I want to have a different 
cache for each value of this parameter.

Now as long as the links in the pages don't include a cHash query 
parameter, the cache hash calculation is not triggered (even when my 
variable is added to config.linkVars).

The only option I see for now is to try and ensure that the cHash is 
added to all links, which I'm not sure is really achievable.

Did I miss something? Is there some parameter associated with this new 
calculation that makes it possible to have some extra parameter taken 
into account without needing cHashes on every link? (I think not by 
looking at the source code).

Cheers
