Unfortunately, our search server doesn't support Accept-Encoding and I didn't see a way to use gzip (or any other tool that came immediately to mind) to do deflate encoding, but here are some results from compressing various forms of the same data: search results for mesages on this thread --- RDF/XML: spam:/home/eric$ GET -H 'Accept: application/rdf+xml' 'http://www.w3.org/Search/Mail/Public/search?keywords=&hdr-1-name=subject&hdr-1-query=ACTION%3A+elaborate+on+4.4&index-grp=Public__FULL&index-type=t&type-index=public-rdf-dawg&resultsperpage=100' > asdf && gzip asdf && gzip -l asdf.gz && rm asdf.gz compressed uncompressed ratio uncompressed_name 2171 30342 92.9% asdf N3: spam:/home/eric$ GET -H 'Accept: application/x-n3' 'http://www.w3.org/Search/Mail/Public/search?keywords=&hdr-1-name=subject&hdr-1-query=ACTION%3A+elaborate+on+4.4&index-grp=Public__FULL&index-type=t&type-index=public-rdf-dawg&resultsperpage=100' > asdf && gzip asdf && gzip -l asdf.gz && rm asdf.gz compressed uncompressed ratio uncompressed_name 1924 20439 90.7% asdf and, for yucks, HTML: spam:/home/eric$ GET -H 'Accept: text/html' 'http://www.w3.org/Search/Mail/Public/search?keywords=&hdr-1-name=subject&hdr-1-query=ACTION%3A+elaborate+on+4.4&index-grp=Public__FULL&index-type=t&type-index=public-rdf-dawg&resultsperpage=100' > asdf && gzip asdf && gzip -l asdf.gz && rm asdf.gz compressed uncompressed ratio uncompressed_name 6377 31971 80.1% asdf -- -eric office: +81.466.49.1170 W3C, Keio Research Institute at SFC, Shonan Fujisawa Campus, Keio University, 5322 Endo, Fujisawa, Kanagawa 252-8520 JAPAN +1.617.258.5741 NE43-344, MIT, Cambridge, MA 02144 USA cell: +1.857.222.5741 (does not work in Asia) (eric@w3.org) Feel free to forward this message to any list for any purpose other than email address distribution.
