Leif Hedstrom created TS-4025:
---------------------------------
Summary: Consistent hashing in parent.config can use suboptimal
URL for hash
Key: TS-4025
URL: https://issues.apache.org/jira/browse/TS-4025
Project: Traffic Server
Issue Type: Bug
Components: Parent Proxy
Reporter: Leif Hedstrom
In a setup, where the same assets can have different URLs (e.g. query
parameters, or two paths normalized to the same cache key), parent proxy can be
suboptimal. This is TS-4020, and the solutions would be similar; Use the cache
key (CacheInfo->md5) which is internally what we call LookupURL. LookupURL is
that URL that plugins modify to change the cache key.
This has to be rolled out carefully as well, we're thinking something like
6.x - We add a new configuration, that lets you use the LookupURL for the hash
(default off)
7.x - We change this new configuration to be enabled by default
8.x - We remove this configuration.
This Jira tracks the first step, we'll file subsequent Jira's for 7.x and 8.x.
