Hi Daniel !
Great Tool. Ok i will switch from my script to yours, but before i have a few question.
1) we need a place to accounte things like for tool.
2) At the moment i can access the php via http://tools.wikimedia.de/~daniel/foo/WikiProxy.php?wiki=de&title=Haus That works with de and en. But if i use fr for example that doesnt work. Ok you wrote only de/en will be cached. but perhaps you can make the tool working for no-cached languages ?
3) what about cache-expired-time ?
4) Perhaps we can have a small space from the toolserver to tmp more request ?
