You need DEBUG=httpcore, since almost all of the core HTTP functionality 
lives in net/tcp/httpcore.c.  DEBUG=http will enable debug only for 
net/tcp/http.c, which contains only the structure defining "http://" as 
a URI scheme.

For reference: DEBUG=httpcore will show you any HTTP errors. 
DEBUG=httpcore:3 will also show you all transmitted and received 
headers.  If you're debugging optional extra components (such as HTTP 
Basic or Digest authentication) then you'll need to add httpbasic, 
httpdigest, etc.
