[TYPO3-english] How to pass a parameter through a whole TYPO3 site in 4.5 respecting caching?

[Jan Kornblum]

Hi newsgroup,

i have to pass a parameter through a whole TYPO3 site. The parameter 
acts like a "partner-id". How can this be achived best in TYPO3 4.5 
without leading to a wrong caching behaviour?

The install tool options [1] "cHashRequiredParameters", 
"cHashOnlyForParameters" or "cHashExcludedParametersIfEmpty" do not yet 
exist in 4.5 LTS.

The only solution i've found is setting no_cache=1 as soon as the 
parameter is passed:

config.linkVars = L, myParam
[globalVar = GP:myParam > 0 ]
page.config.no_cache = 1
[global]

But is there any other and better possiblity to pass "myParam" without 
having to set no_cache=1? I'm aware i could store my param into the 
fe_user session, but this is not whished in this concrete case :(

Kind regards, Jan
