A) Normal non-proxy HTTP:

 - no more "Pragma: no-cache" (this only makes sense to proxies)

B) Non-CONNECT HTTP request over proxy:

 - "Pragma: no-cache" is used (like before)

 - "Proxy-Connection: Keep-alive"

for the given test case. This should fix the cases where the server can run
but curl cannot work with it.

why sometimes the control connection dies after a RETR has been sent
