Subject Re: Push Cache
Date Mon, 04 Feb 2013 13:04:40 GMT

Thank you for your reply, and you are absolutely right, here are more
details on how I'm using ATS and what I want to get from it.

I am using trafficserver 3.2.0 as a forward proxy. And what I'm looking for
is to push some web pages into the cache, and then restore them using my
browser (FireFox 7.0.1), yet I was not able to do so.

When i try pushing a website into my ATS cache I always get the OK
response, but when I try loading the page using my browser I get the actual
page not the one I pushed into the cache. Therefore I tried using wget.
With wget if I dont use --no-proxy flag I get the actual webpage again (the
"original index.html") but using wget with no flags I get the exact same
materials I push to the cache. I asked this before (not ver verboosly
though) and a gentleman mentioned that it can be because of my browser,
this is his original reply, but I cant take his notes further...

So here is some part of my records.config :

CONFIG proxy.config.http.server_ports STRING 8080
CONFIG proxy.config.http.connect_ports STRING 443 563
CONFIG proxy.config.http.insert_request_via_str INT 1
CONFIG proxy.config.http.insert_response_via_str INT 0

CONFIG proxy.config.url_remap.default_to_server_pac_port INT -1
CONFIG proxy.config.url_remap.remap_required INT 0
CONFIG proxy.config.url_remap.pristine_host_hdr INT 1

And I only have this line uncommented in my ip_allow.config:

src_ip=                                  action=ip_allow

Thank you for your time.
