Hi Grisha,

    I have compiled the latest CVS version, and it works.
But I found another problem here.

>  postData = filter.read()
>  modify(postData)
>  filter.write(postData)

If postData's length is not changed, everything is fine. 
Otherwise IE will hand there.
I guess this is caused by HTTP header "Content-Length" .
Because we changed the request body, but didn't update the header.
