[jira] [Commented] (TS-1577) Crash report:
RangeTransform::change_response_header at Transform.cc:995
[ https://issues.apache.org/jira/browse/TS-1577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13539158#comment-13539158 ]
weijin commented on TS-1577:
----------------------------
try to solve the problem in ts-1574, ts-1577
If there is a copy in cache (expire), range request can invalidate it. If the original server response 304, serve from cache.
the current cache codes and still can not support do_io_pread if read_from_writer. If the content_length of cache copy is INT64_MAX (a special case of read_from_writer), just proxy the request to server.
