Re: [users@httpd] mod_ratelimit working by steps ?
I created a 4MB file and rate limited its directory container in the
httpd's conf, and tested 8/20/30/etc.. settings as you suggested with
curl http://localhost/test.txt > /dev/null (in this way I drop the
returned response but keep the curl's connection metadata summary).
In every case I get the expected result (average Dload speed).
Thanks a bunch for testing this, and confirming that something is wrong
on my side.
After more test, I'm pretty sure the problem come from a bad interaction
between mod_ratelimit and mod_proxy.
(sorry, I forgot to mention that the path I was trying to rate-limit is
indeed a tomcat app behind mod_proxy).
Did you execute your performance tests in localhost? And also, did you
use another tool other than Firefox? I'd be curious to know your
results with curl executed in localhost.
I've tried the following (Excerpts from my config at the end of this
0) rate-limit on tomcat app proxified throught mod_proxy (previous mail)
=> rate-limit works by step, and does not limit anything if
rate-limit > 40
(tried on local with wget)
1) rate-limit on a true folder, served by apache :
=> rate-limit is working as expected
2) rate-limit on file served through python's SimpleHttpServer,
proxified by mod_proxy
=> rate-limit works by step.
In conclusion, tomcat is not at fault, since python's SimpleHttpServer
also have a problem, and the trouble come from my reverse-proxy.
In the case af a reverse proxy, I'm not sure which part of the
connection get rate-limited ?
Is that an known problem ?
Or am I trying to do something totally bogus here ?
Any ideas to achieve my goal ? (that is, limiting the bandwith used by
the tomcat app)
PS : for what it's worth, I've tried 1) with curl, and got the following
error, wich seems to be related to the use of http2:
curl: (56) Unexpected EOF
wget is fine, though.
PS2 : Excerpts from my config
Allow from all
<Location /airsonic> # the tomcat app
SetEnv rate-limit 35
<Location /test> # a true folder, served by apache
SetEnv rate-limit 50
<Location /test2> # a python SimpleHttpServer
