I've turned on the experimental SDCH compression protocol by default for the ".google.com" domain only. Currently Google is helping to test support by serving some web pages using this protocol (to browsers that support it), so this default change will only impact search at google.com If things go well, I'll enable it for the entire net in a week or two.
Please report bugs or problems with search if you see any. The (new/current) default is equivalent to starting chrome via: ./chrome.exe -enable-sdch=.google.com If this horks your build, and blocks you, you should run with an explicit enable supplying a non-existent domain, such as: ./chrome.exe -enable-sdch=.nonexistantdomainthatyournotworriedabout.com If you're testing out serving the SDCH protocol from your server (other than *.google.com), you can fully enable SDCH support in Chromium via: ./chrome.exe -enable-sdch FAQ What is SDCH? It is a delta-compression protocol. The server provides a dictionary, and then can send results "relative" to that dictionary. Where can I read more about it? Take a look at http://groups.google.com/group/open-vcdiff/browse_thread/thread/8c4bf1dd91a56ac9?pli=1 How does chromium support it (roughly)? Chromium advertises its support of "sdch" in its Accept-Content header (i.e., where it also says it supports gzip, deflate, etc.). A supporting server then sends back (in a response header) an URL to get a dictionary "for future use." Chromium gets the dictionary about 15 seconds later (to avoid interfering with the current download). Chromium then advertises both support for "sdch" as well as its possession of the dictionary to the appropriate domains. A domain's server that recognizes the dictionary then compresses future payload responses using the delta-compression (commonly in concert with gzip compression). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Chromium-dev" group.
