> -----------------------------------------
>
> Key: TS-1827
> URL: https://issues.apache.org/jira/browse/TS-1827
> Project: Traffic Server
> Issue Type: Improvement
> Components: Plugins
> Reporter: Conan Wang
> Assignee: Leif Hedstrom
> Fix For: 3.3.3
>
>
> Based on TS-1053, I've made some minor improvements. Community can select the
> general ones to review.
> Changes: (separately pasted on pastebin temporally; may provide with commits
> later after TS-1053 is solved on git master):
> # use HOST header as default bucket http://pastebin.com/pGHfLaHR
> Original code use the first segment of Host as the default bucket and it's
> not that expandable (two different combo domain may have same leading
> segment). Moreover, the initial default bucket("l") will not be used, because
> all requests should have a HOST.
> # sub-file's path need to contain querystring, i.e. question mark("?") is
> part of the file path, not the delimiter http://pastebin.com/HvMJBQw0
> We use querystring to version each single sub-file in the combined url. If we
> want to update/purge one of them, it can be simply accomplished by changing
> the version of sub-file. (If not, you have to purge both the combined url and
> sub-file url which is relatively hard to know the latter one when you are not
> very familiar with ATS. Of course you can alter the filename if possible in
> your site.)
> Then the combo url could be like
> http://example.com/combo?file1?v=2012&file2?v=2013
> # request hangs when combo url has no querystring http://pastebin.com/d34ZJDzQ
> # make plugin per-remap enabled/disabled http://pastebin.com/YTaDYvh2
> It's implemented by adding some remap code and make global part "intercepted"
> in TS_EVENT_HTTP_OS_DNS instead of TS_EVENT_HTTP_READ_REQUEST_HDR in order to
> read the flag set in TSRemapDoRemap.
> So remap.config will be: {code}
> map http://example.com http://os.example.com @plugin=combo_handler.so
> map http://localhost/example.com http://os.example.com
> map http://other.com http://os.other.com # combo for this channel is
> disabled
> {code}
> # limit sub-file max count and querystring length for potential problems
> http://pastebin.com/cmBCuCNB
> # log failed url http://pastebin.com/bNezeaz0
> They were tested on 3.0.x.
