redirect response in cache
[ https://issues.apache.org/jira/browse/TS-3140?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Leif Hedstrom updated TS-3140:
------------------------------
Backport to Version: (was: 5.2.1)

> -----------------------------------------------------------------
>
> Key: TS-3140
> URL: https://issues.apache.org/jira/browse/TS-3140
> Project: Traffic Server
> Issue Type: Bug
> Components: HTTP
> Affects Versions: 5.0.1
> Reporter: zouyu
> Assignee: Susan Hinrichs
> Labels: crash, review
> Fix For: 5.2.1, 5.3.0

> Traffic server will crash in below steps:
> 1. Enable redirect and http cache, make sure that traffic server can cache redirect request & redirect response such as 302/307 response.
> 2. make a remap url in traffic server which will remap to a redirect url 'redirect_url_1' which points to 'www.google.com' ( note that 'www.google.com' is also a redirect url which may point to 'www.google.com.sg')
> 3. make number_of_redirections=1 in records.config.
> 4. access the 'redirect_url_1'. At first time, after access it, traffic server will cache the redirect response such as 307.
> 5. try to access the 'redirect_url_1' again, this time traffic server will crash.
> The root cause is that in above case, traffic sever will check the cache in a loop definitely which will exhausted the stack space.
