[TYPO3-dev] Restricting GET parameters / Caching

[Michael Knoll]

Hello list!

We have a problem with caching in a TYPO3 website with high traffic. The 
problem is that each combination of GET parameters is cached, even if 
they make no sense.

Instead of http://domain.com/ one can use http://domain.com/?key=value 
and each time a different GET parameter is used, the resulting page is 
cached individually.

So there are 2 questions:

1. Can I restrict the parameters on a per-site configuration? If yes, 
where can I find some documentation on that topic? A whitelist of 
expected parameters would be great.

2. Can I create redirect with a HTTP 301 (moved) if denied GET 
parameters are used.

As I think that a solution for this problem is interesting for other 
developers as well, I posted this question here.

Thanks a lot in advance!
