redirect everything with a ? after the domain

[zeus]

Ohh man I have never done so much redirecting on site like the last 2 years, be cause google simply spiders everything. The new problem is, I have a ton of duplicated versions of my frontpage, they all looks something like this after the domain:

/?id=2323
/?cat=bla&start=200

so how can I redirect everything to the domainname or the real page without the blabla you see.

Check recent threads. There are five in the last week discussing redirects and parameters.

I have searched google for 2 hours tried all kinds of solutions, nothing works

Let's see the code, what it was supposed to do, what it did, and how that differs from what you wanted.

Do you want to redirect humans or just stop the duplicate pages from being indexed? Have you been to the Ignore Parameters area of WMT?
