--------------------------------
Summary: API: Cached URL MLocs prevent the HttpSM from detecting
Url Changes.
Key: TS-3061
URL: https://issues.apache.org/jira/browse/TS-3061
Project: Traffic Server
Issue Type: Bug
Components: Core, CPP API, TS API
Reporter: Brian Geffon
Assignee: Brian Geffon
The HttpSM contains a cached version of the client request url to avoid
re-generating strings repeatedly. The problem is that if a plugin caches the
MLoc and MBuf they can modify the URL without the cached copy being updated.
Unfortunantely, moving the dirty flag into UrlImpl would be incredibly messy,
so I will propose that after api callouts are complete we mark the cached url
as dirty. It seems like the only reasonable approach that has minimal
performance impact while maintaining the caching.
