'''SDCH'''（{{langx|en|'''Shared Dictionary Compression for HTTP'''}}）是[[Google]]基于{{tsl|en|VCDIFF|VCDIFF}}（RFC 3284）创建的[[数据压缩]]算法。它已在最近版本的[[Google Chrome]]、[[Chromium]]和[[Android]]中支持，并被Google系列网站支持。<ref>{{Cite web|url=http://lists.w3.org/Archives/Public/ietf-http-wg/2008JulSep/att-0441/Shared_Dictionary_Compression_over_HTTP.pdf|title=A Proposal for Shared Dictionary Compression Over HTTP|publisher=Google|last1=Butler|first1=Jon|author2=Wei-Hsin Lee|last3=McQuade|first3=Bryan|last4=Mixter|first4=Kenneth|accessdate=2016-07-01|archive-date=2016-04-15|archive-url=https://web.archive.org/web/20160415071632/http://lists.w3.org/Archives/Public/ietf-http-wg/2008JulSep/att-0441/Shared_Dictionary_Compression_over_HTTP.pdf|dead-url=no}}</ref><ref>{{Cite web|url=https://groups.google.com/forum/#!forum/SDCH|title=SDCH Mailing List|publisher=Google Groups|accessdate=2016-07-01|archive-date=2011-01-22|archive-url=http://arquivo.pt/wayback/20110122130054/https://groups.google.com/forum/#!forum/SDCH|dead-url=no}}</ref><br />
