[aida] failure in parsing HTTPRequestLine

Now I know what is a problem and it is patched (I cannot say solved:) in
latest Swazoo 2.1.
Namely POSTs are somehow not parsed completelly and it seems a byte or
so sometimes stay unparsed. But parsed content is correct anyway. That's
why I didn't go deeper (besides I didn't have time). Quick solution is
simply to close connection after a post and that's in Swazoo 2.1 in
method HTTPConnection produceResponseFor: .
Because POSTs are relatively rare comparing to GETs I think such quick
problem solution won't affect Swazoo performance in general.
I hope this help a bit

I get one correct POST request and then i get the same one again, but this time only a part of the post data. And on trying to get the request type occurs the error. I am not sure why this happens, perhaps why the post data seems not to be parsed?
