Is breaking this test going to cause an issue?
Issue Time Tracking
-------------------
Worklog Id: (was: 30983)

> backslash/escape removed from header_rewrite rule when unquoted
> ---------------------------------------------------------------
>
> Key: TS-4993
> URL: https://issues.apache.org/jira/browse/TS-4993
> Project: Traffic Server
> Issue Type: Bug
> Components: Plugins

> Reporter: Randall Meyer
> Assignee: Leif Hedstrom
> Fix For: 7.1.0

> Loading up a configuration with a header_rewrite rule of:
> {noformat}
> cond %{READ_RESPONSE_HDR_HOOK} [AND]
> cond %{PATH} /(\.html|\.js|\.png)(?:\?(.*))*$/ [AND]
> cond %{STATUS} >199 [AND]
> cond %{STATUS} <300
> set-header Cache-Control "max-age=31536000, public
> {noformat}
> results in an call to abort() in matcher.h under ATS 7.0.0. This worked fine
> under ATS 6.x (and probably 5.3.x)
> {noformat}

> {noformat}
> The string comes to matcher with the escapes removed:
> {noformat}
> Adding condition: %{PATH} with arg: /(.html|.js|.png)(?:?(.*))*$/
> {noformat}
> If I add quotes around the regex, this regex is passed through correctly
> escaped.
> Not sure if this is expected behavior or not.
> This also seems related to TS-4797 and TS-4940.
