Description johansen 2009-05-13 13:55:10 UTC

The current transport mechanism uses a POST request to perform file downloads. 
The problem with this approach is that the POST request is opaque and cannot be
cached.  We need to switch to downloading pkg content using a HTTP method that
is cacheable.  Piplined GETs show the most promise right now.  I have a
prototype that uses libcurl/pycurl to accomplish the downloads.  At the moment
its performance is on-par with the performance of the existing transport.

Marking RFE and setting target milestone.

This bug is being fixed as part of the transport re-design.  A preliminary
webrev is available from:

Bug 8903 depends upon some of the functionality delivered by 8902, clearing
depends on entry, instead of introducing a circular dependency.
