[jira] [Updated] (TS-2307) Range request with If-Range does not
work
[ https://issues.apache.org/jira/browse/TS-2307?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jungwoo Lee updated TS-2307:
----------------------------
Description:
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] == '/'))
- 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.
