Alan M. Carroll commented on TS-3140:
-------------------------------------
What's the expected behavior here? I think that if redirect following is
enabled, ATS shouldn't cache a redirect, it should follow it. Is the cache
happening because the # of redirects has been exceeded?
> Traffic server crashes when there is a redirect response in cache

> Issue Type: Bug
> Components: HTTP
> Affects Versions: 5.0.1

> 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.
