[PATCH] Why bother about r->main in webdav write through proxy code?

Hi All,

I was going through the webdav write through proxy filter code.
I could see check for 'r->main' in it.

I tested the following,
1. slave writing to different master host.
2. slave writing to same master host instance but on a different uri.

In both tests I could 'r->main' is always null.

I am not sure why we should bother about sub request inside by checking
for r->main?

Attached patch removes such checks.

Any thoughts?

With regards
Kamesh Jayachandran
