Jungwoo Lee commented on TS-2307: --------------------------------- This will be occurred when ETAG does not include " on start and end of ETA > Range request with If-Range does not work > ----------------------------------------- > > Key: TS-2307 > URL: https://issues.apache.org/jira/browse/TS-2307 > Project: Traffic Server > Issue Type: Bug > Components: HTTP > Affects Versions: 3.2.5, 4.0.1, 4.0.2 > Reporter: Jungwoo Lee > Labels: A > Fix For: 4.2.0 > > > 1. Precondition > - Upload file such as video or music file on Origin server > - On Chrome, access to the content file > - Repeat followings > -- Delete the cache of Chrome > -- Refresh( press F5 ) > 2. Result > - Chrome does not play the content. > 3. Cause > - When Chrome requests including Range and If-Range headers, the value of > If-Range header can be set to the one of ETAG and Last Modified Date. ATS > core has unreasonable condition to check if the value of If-Range is ETAG and > it makes a bug that the value of If-Range will be compared with Last Modified > Date event if ETAG is set to the value of If-Range. > As a result, response header does not include Content-Range when the value of > If-Range is ETAG. Sometimes this makes client abort. > - The condition to check ETAG is following( > HttpTransactCache::match_response_to_request_conditionals(HTTPHdr * request, > HTTPHdr * response) function ) > -- if (!if_value || if_value[0] == '"' || (comma_sep_list_len > 1 && > if_value[1] == '/')) > --- when ETAG doesn't start and end with " this condition will be failed. > -- The if_value points the string of value of If-Range > 4. Expected Behaviour > - Video and music file will be played in all the time on all case. > -- When the value of If-Range is ETAG and is matched with ETAG of header of > cached content , response should include the header related with range > request. -- This message was sent by Atlassian JIRA (v6.1#6144)
