Comment:

 (In [4042]) Previously, we forced the request to "GET" on all fetches for
 cache
 and this prevented users from implementing "purge on POST" semantics
 by looking up the POST requests and ditching the object found.

 Now we only overwrite the request with "GET" if it is a HEAD, (the
 internal "wantbody" flag tells hos how the response should be composed.)

 The testcase shold probably be elevated to VCL example, with suitable
 footnotes about URL sanitizing etc.

 Fixes #444
