Intercept Plugin
Hi,
I am using atscppapi intercept Plugin. Does it still require a remap rule
if I am using SERVER_INTERCEPT type. I just want to respond with a custom
response if I see a specific url. Thanks.
Dk.

Thanks. I think after cleaning up the config and reloading everything,
things seem to be working fine with the custom plugin.
Thanks everyone for the help.

Hi,
The " Not Found on Accelerator " and "Multi-Hop Cycle" logs seem indicate that ATS itself is acting as parent/origin for some urls, maybe you should take a deeper look at your config files.

Hi Alan,
I tried to add a remap rule like this:
regex_map http://(.*)/(.*) http://$1/$2
I still get the following error:
20160314.19h04m03s RESPONSE: sent 127.0.0.1 status 404 (Not Found on

So I tried your suggestion #2 and set the remap_required to 0 (didn't want this but wanted to try it out).
I got the following error...

I wouldn't bother with that complex of a remap rule - just turn off remap required entirely.
http://trafficserver.readthedocs.org/en/6.0.x/reference/configuration/records.config.en.html#proxy-config-url-remap-remap-required
If that doesn't work you'll need to turn on debug tags "http|remap" to see what's going on.

is there another way where the TS (or plugin in TS) can act as a server?
thx.

Traffic Server requires either (1) a remap rule or (2) disabling remap_required in records.config. This is not specific to the intercept plugin. If you don't want (2) you can always add an identity remap to remap.config and map the URL to itself.
Re: Intercept Plugin

no luck. I am still stuck with the same error...
20160314.02h43m20s RESPONSE: sent 127.0.0.1 status 404 (Not Found on
Accelerator) for 'http://...'
Since it cannot find a remap rule, it never invokes
the HOOK_SEND_REQUEST_HEADERS hook.
As a result, my custom plugin never gets invoked. I was running into the
same issue with intercept plugin.
I even tried skipping remapping by calling TSSkipRemappingSet in
readRequestHeaders hook, that just
gives me a different error...
20160313.22h51m01s RESPONSE: sent 127.0.0.1 status 400 (Multi-Hop Cycle
Detected) for 'http://....'

The example I was referring to is here:
https://github.com/apache/trafficserver/blob/master/lib/atscppapi/examples/customresponse/CustomResponse.cc
In CustomResponseTransactionPlugin::handleSendResponseHeaders() you can
manipulate the response in any other ways you want, in this example it
changes there response status code and message (the body was set w/
.error() in the constructor, but like I said you can also set headers or do
anything else.

Take a look at the example, you can set the body, status code, headers,
basically anything you want. The only reason you might want to use an
intercept plugin is it you wanted to stream a response.

custom error message plugin doesn't seem to include body. I wanted to

I would suggest looking at the custom error response plugin in the examples
folder, it will give you same result and it's much easier,
