Apache Traffic Server Hierarchical Caching Question
HI,
I am new to Apache Traffic Server. I am interested in setting up a Hierarchical Caching environment. I have read the documentation and as I read it, it states that only parent.config and records.config need to be modified on the child server. As a test, I am accessing an HTML page on child from a client. The page is not on the child but exists on the parent. For some reason, I receive a 404 error. Is there something that I am missing.
Thanks
Ken

Now that I'm finally done with tuning my setup, I can offer some help if you still need it.
I have a simple one child, one parent forward-only proxy setup that's up and running.
I also have a webserver running on the parent and accessing it via the proxy hasn't been a problem.
Let me know if you'd like a copy of my configs, etc.
You may be stuck on this part. This config line is from parent.config on my child proxy:
dest_domain=. parent="sparkle.adamdace.info:8080<http://sparkle.adamdace.info:8080>"

This doesn't sounds like parent proxying, just normal reverse proxying
Does origin.mytest.com run a web server, like Apache HTTPD ? One guess could be the pristine host header setting in records.config on the Traffic Server. Depending on what your origin expects to see, you have to set this setting properly.
If origin.mytest.com expects to see "Host: origin.mytest.com", then the pristine host header setting should be off (0). If origin.mytest.com expects to see "Host: traffic.mytest.com", then it should be on (1).
Other than that, hard to say. You need to look at logs on both sides, and perhaps run ATS with a tracer (e.g. -T http) to see what it does.

Leif,
I still have an issue.
To simply matters, I am trying to set up a reverse proxy server. I have 2 servers: traffic.mytest.com and origin.mytest.com. Both servers are running Apache Web Server. The index page is only on the origin server. I modified the traffic server as follows:
remap.config
map http://traffic.mytest.com http://origin.mytest.com
reverse_map http://origin.mytest.com http://traffic.mytest.com
records.config
CONFIG proxy.config.reverse_proxy.enabled INT 1
I then stop and start the trafficserver.
On a browser on a client, I enter:
http://traffic.mytest.com/index.com
I expect the traffic server to make an HTTP request to the origin server and then cache the page on the traffic server. The traffic server will then server the page to the client. However, I get and Error 404.
Am I understanding this correctly?
Thanks in advance for your time and help.
Ken

Hard to say, but a wild guess could be one or all of the settings below. otherwise, you might need other configs, such as remap.config for example.
Forgot to say, in a setup like this, make sure that you parent proxy everything, otherwise you could open up things as an open proxy (which you don't want).
