SDCH (Shared Dictionary Compression for HTTP)

[ericlaw1979]

Will IE/Edge implement SDCH? It's in Chrome and gives good results.

https://engineering.linkedin.com/shared-dictionary-compression-http-linkedin The data we collected compares gzip with sdch+gzip. When sdch and gzip are combined, we have seen additional compression as high as 81% on certain files when compared to gzip only. Average additional compression across our static content was about 24%. Google says: About 40 percent data reduction better than Gzip alone on Google search.
