[wp-hackers] WP_HTTP deflating small packets

[Dion Hulse (dd32)]

Yes, WordPress is adding request headers to say what it supports, and it
supports deflating and decompressing the return values.
Now, the question is why it's not working correctly for you.

The first step is to figure out which HTTP transport is in use, This could
be cURL (but, hopefully it isn't). Throw some debugging in
WP_HTTP::request() and get the class_name() of the actual http transport in
use.

The 2nd step is being able to reproduce it. Every server will return content
in a different way, if you can setup a page on a host somewhere (just a
static document) which reliably reproduces it, that would be really good.

The 3rd step is working out if the extra headers shouldn't be added for that
transport, or if someone forgot to call the decompression/encoding functions
on that transport correct, or if the server is simply doing something
strange and not following the spec 100% (Which is very common, most have
their little issues that clients just work around)
