A couple of things to try -
1) Drop the :80
2) Turn on debug tags with a value of "http|dns" and see what you get. Those
tend to be informative in this regard, as you will be able to see exactly what
ATS thinks it is connecting to.

{}#yiv2744081655 Ah, thank you very much, updating the maps did change things!
Right now I am getting error messages that kinda make sense. So, here’s my
new remap settings: map http://mediawiki.mycompany.com:8080/
http://localhost:80/ reverse_map http://localhost:80/
http://mediawiki.mycompany.com:8080/ When I try to
hithttp://mediawiki.mycompany.com:8080/phpinfo2.php in the browser now, I get a
502 response after a lengthy timeout: internal error - server connection
terminated and on the server, in error.log, the following gets recorded:
20160120.14h51m15s RESPONSE: sent 10.87.40.108 status 502 (Connect Error
<internal error - server connection terminated/-19999>) for
'http://localhost:80/phpinfo2.php' I tried this both using localhost in the
maps, and FQDNs everywhere, the result is the same. I most definitely can get
this URL on the server using curl: $ curl -Is
http://localhost:80/phpinfo2.php | grep ^HTTP HTTP/1.1 200 OK So it looks
like for some weird reason, TrafficServer is trying – and failing – to contact
the origin provider. Any idea what might be going wrong? Thanks so much
for your help! From: Alan Carroll [mailto:[email protected]]

Subject: Re: Need help with a particular usage scenario Hmmm. A parent proxy
set up might work better. The logging of empty URLs is a bug in the logging
code which has been fixed (current ATS version is 6.0). If you are doing remap,
you need a forward map as well like maphttp://mediawiki.mycompany.com:8080/
http://mediawiki.mycompany/ reverse_map, if I recall correctly, only applies
to response headers from the origin, to modify them to use the proxy URL
instead of the origin URL (as supplied by the origin). I'd recommend moving
up in versions, to at least 5.3.x. On Wednesday, January 20, 2016 12:23 PM,

set up a caching proxy to not work as a proxy, but rather to simply provide
caching upon direct access. For example: There’s a Mediawiki installation
running athttp://mediawiki.mycompany.com And I need to set up a proxy on an
alternative port,http://mediawiki.mycompany.com:8080, which would do nothing
but serve up the traffic from the default port, but cached (we aren’t trying to
cache the entire MediaWiki installation, but rather provide an alternative
entry point for a specific use case). I am having trouble figuring out what
it would take to set up TrafficServer to do this. I set it up (Ubuntu Vivid, TS
3.2.4), but TS logs empty URLs (http:///) and of course fails to find them –
presumably because it doesn’t receive the customary proxy HTTP headers; so I
hithttp://mediawiki.mycompany.com:8080, and only get back 404s. Is there an
easy way to accomplish what I am looking to do? Here’s the config I have right
now. In records.config (in addition to all the standard defaults): CONFIG
proxy.config.http.server_ports STRING 8080 CONFIG proxy.config.http.cache.http
INT 1 CONFIG proxy.config.reverse_proxy.enabled INT 1 CONFIG
proxy.config.url_remap.remap_required INT 1 CONFIG
proxy.config.url_remap.pristine_host_hdr INT 1 And in remap.config:
reverse_maphttp://mediawiki.mycompany.com/ http://mediawiki.mycompany.com:8080/
I have never set up a proxy before. Any suggestions on what I need to do?
Thanks.
