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

Hi Stephen,

thanks for your reply.

But defaultGetVars seems to *always* add the defined params to the 
link. I want the param only to be added when the site has been called 
with the param before.

Also, i need "myvar" to be capable of dynamic values i can't predict 
(like 1,2,3,...,999999).
