Subject Re: [PATCH] dechunking, body filtering
Date Sat, 14 Oct 2000 07:21:06 GMT

I have reviewed the patch in some detail and some parts of it are very
good.  Others I just can't agree with.  Some sketchy comments below.  I'll
make more comments tomorrow morning.

You can't do this.  You can't even garauntee that http_filter will be in
the server.  I have every intention of writing an input filter that takes
ftp requests and converts them to http.  When I do that, there will be no
http_filter in the request, and this will break.  No filter can EVER
depend on another filter being in the stack.

This was discussed yesterday and people really disliked it.  If filters
are told the maximum amount of data they can return, this is unnecessary.
