Hi, I’d like to propose a change about the timing that ATS runs remap plugins.
Currently, we configure remap.config like the following snippet, and each plugins use `rri->requestUrl`, the behavior of a remap plugin as the first plugin is different from that as the second plugin. ``` map http://before-remap.com/ http://after-remap.com/ @plugin=<first plugin>.so @pparam=... @plugin=<second plugin>.so @pparam=... ``` In detail, the first plugin get pre-remapped url information from `rri->requestUrl`, but the second plugin get post-remapped one. The cause of this behavior is ATS executes `url_rewrite_remap_request` function after running the first remap plugin. My proposal is that ATS should execute all remap plugins and then rewrite url. More ditails are in - Issue : https://github.com/apache/trafficserver/issues/2877 - Pull Request : https://github.com/apache/trafficserver/pull/4531 What do you think about this? Thank you.
