Hello,

I just released v0.9.0 of dlang-requests. This is large 
performance improvement and code refactoring release. Nothing 
changed in API and everything should work as before (hopefully 
better and faster)

What's new:

1. Connection pool for each HTTPRequest structure added. This 
give huge performance gain if you repeatedly call rq.get/post/... 
and/or when redirects involved.

2. Cache for permanent redirects added to Request structure.

As result started from test results

(amazon recognise curl and send very short reply, so for curl it 
work faster anyway)
