Folk, I've tried digging through the manual but haven't found any hints.... Is there any way to configure Import["http..."] to request Gzip compression (or otherwise customize things like the Use-Agent without resorting to using J/Link)? I know Mathematica supports GZIP as a file based import, but I'm wanting it to request compressed data from the http server (Generally requires 'Accept-Encoding: gzip, x-gzip, deflate' being sent in the http request/headers). I've got an issue where Import seems to silently fail when the remote host is sending data over a latent link and I know that using gzip compression has resolved similar issues with Perl/LWP for me in the past... I put in a ticket w/ Wolfram on this on THURSDAY and have yet to receive any response from support....  It fails to the point where a Print after the Import inside a Module doesn't even run(!) when the link latency (I think this is the catalyst anyway) is high enough. -jbl
