stats_over_http.so is causing a loop

[edd! <me...@eddi.me>]

Hi,

On ATS 8.0.7 stats_over_http.so is causing a loop; here's the config:
plugin.config: stats_over_http.so statz
remap.config: map http://10.0.34.1:80/statz http://{cache}/statz
@action=allow @src_ip=10.10.10.10

As soon as I request the page I get countless errors in access.log
10.0.34.1 | ERR_CONNECT_FAIL | NONE | MISS | WL_MISS | 502 | 478 | GET |
http://10.0.34.1/favicon.ico | - | DIRECT/10.0.34.1 | text/html
10.0.34.1 | TCP_MISS | NONE | MISS | WL_MISS | 403 | 442 | GET |
http://10.0.34.1/statiztikz | - | DIRECT/10.0.34.1 | text/html

and in diags.log:
[ACCEPT 0:80] WARNING: too many connections, throttling.
 connection_type=ACCEPT, current_connections=30002,
net_connections_throttle=30000

Only restarting trafficserver stops this loop.

Thank you,
Eddi

It is expected that ATS would loop, as the address you put in the browser
is where ATS will try to connect. If that's the ATS address, then it will
connect to itself and loop. With a correct configured stats_over_http, the
plugin prevents ATS from connecting outbound, preventing the loop. Instead
the plugin directly serves the response. Reading the documentation, it
looks to me that you should configure just the plugin and not have a remap
rule for it.

I removed the stats_over_http from the plugin.config and removed the map
rule but still, whenever I enter the trafficserver ip in a web browser it
loops endlessly.
So it has nothing to do with the stats_over_http plugin

I don't understand your remap rule. According to the documentation, there's
no need to do a remap at all. Even if needed, I think the path
"[cache}/statz" isn't going to work, as the "{}" paths are special and
don't generally have additional path information. If you leave out the
remap rule, does it still work?

Another interesting and dangerous addition to the above, I have removed the
plugin and the map then requested the ATS server ip in a browser
http://10.0.34.1, the loop occurred as well
