A rate limit plugin for caddy
Home Page: https://caddyserver.com/docs/http.ratelimit
License: MIT License
I have a lot of paths directly under /
. Just about every resource should be ratelimited, except for static resources like Javascripts and CSS, which don't strain the server much and also need to be accessed frequently. It would be great to be able to apply a ratelimit to all paths except for some, like:
ratelimit 30 1 minute {
[^resources]
}
โ is it possible to limit requests based on their method? For example limiting POST requests.
I would want to use a daily rate limit for a specific project.
Could this feature be added?
There has been some interest in implementing rate limiting within the basicauth middleware to block repeated failed logins (caddyserver/caddy#1318 (comment)), but interest has shifted over to other authentication plugins such as multipass and loginsrv.
However, there is still use for basicauth (e.g. protecting WebDAV, which is my use case), and protecting it from brute force attacks. The problem with a simple
ratelimit * /dav 2 3 second
webdav /dav {
...
}
is that rate limiting will be triggered not only by incorrect credentials (403 responses) but also by legitimate requests (2xx). This is a problem as one might not want to rate limit legitimate requests (or have a much higher rate limit, since certain use cases such as a client doing a sync may generate a lot of requests).
As far as I can think of, this could be done if ratelimit could be configured with a count_if
, which determines which requests count to the request quota of an IP address, and a block_if
, which requests will be denied for an IP address which has already exceeded its request quota and been blocked. Using , for instance, the syntax of if
statements from the rewrite middleware:
ratelimit * /dav 2 3 second {
count_if {status} is 403
webdav /dav {
...
}
Is it possible to look into this feature for caddy-rate-limit?
Would it be possible to add client bandwidth rate limit?
Possibly:
I would like to use these for a specific project in order to limit user downloads.
I use that in Apache for the first one: https://httpd.apache.org/docs/trunk/mod/mod_ratelimit.html
Caddy's import path (and Go module name) has changed from
github.com/mholt/caddy
to
github.com/caddyserver/caddy
Unfortunately, Go modules are not yet mature enough to handle a change like this (see https://golang.org/issue/26904 - "haven't implemented that part yet" but high on priority list for Go 1.14) which caught me off-guard. Using Go module's replace
feature didn't act the way I expected, either. Caddy now fails to build with plugins until they update their import paths.
I've hacked a fix into the build server, so downloading Caddy with your plugin from our website should continue working without any changes on your part, for now. However, please take a moment and update your import paths, and do a new deploy on the website, because the workaround involves ignoring module checksums and performing a delicate recursive search-and-replace.
I'm terribly sorry about this. I did a number of tests and dry-runs to ensure the change would be smooth, but apparently some unknown combination of GOPATH, Go modules' lack of maturity, and other hidden variables in the system or environment must have covered up something I missed.
This bash script should make it easy (run it from your project's top-level directory):
find . -name '*.go' | while read -r f; do
sed -i.bak 's/\/mholt\/caddy/\/caddyserver\/caddy/g' $f && rm $f.bak
done
We use this script in the build server as part of the temporary workaround.
Let me know if you have any questions! Sorry again for the inconvenience.
This plugin needs to support env vars for scenarios like #21 .
e.g. X-RateLimit-Remaining
Hi, any plan to get plugin for caddy v2?
Hi,
we face several sudden death of Caddy during a day and found that deactivating ratelimit solves this.
Our setup:
ratelimit / 300 400 minute {
# 175 whitelisted IP addresses like this:
whitelist x.x.x.x/32
(...)
}
Request statistics:
Increasing available memory of the system does not help and Caddy is not killed by the OOM-killer thus Caddy stops itself for an unknown reason.
My assumption is that the internal structure of the ratelimit plugin does not handle the volume of unique IP addresses well which forces Caddy to stop without any log message.
Are these information enough to analyze the issue?
Best regards,
Andreas
Not an issue - just wanted to write and say thank you for making and maintaining this plugin. It has received probably more praise than you know, and makes quite a few people happy to use Caddy. This plugin is one of the top 10 downloaded. Keep up the great work ๐ and thanks again!
Hi,
we several services with changing IP addresses connecting to our Caddy instance.
These should be whitelisted for the ratelimits.
To allow dynamically adding IPs to the whitelist it would be nice to write those IPs into a file and import that one within a ratelimit block using the Caddy import directive.
Currently the validation fails with the following error:
$ caddy -conf /etc/caddy/Caddyfile -validate 2017/12/18 12:15:22 /etc/caddy/load.d/ratelimit:7 - Error during parsing: expecting whitelist, got import
Would this be possible to implement?
Cheers,
Andreas
Hi, thanks for the extension!
I have a feature request: I'd love to be able to specify units for the rate limit. For example, one request per minute, 10 requests per 5 minutes, 30 per hour, 10 per 20 hours, 100 per week, 2 per year, ... Anything one could imagine

Seems Burst is never used.I used it with burst, but no effect.
So I went into the code, and I can't find the implementation. Is there something I am missing?
Currently, there is no go.mod file specified in the project. As a result, Go pulls in the latest Quic-Go (v0.13.1)
This release has a folder rename, from github.com/lucas-clemente/quic-go/h2quic to github.com/lucas-clemente/quic-go/http3.
Currently, Caddy v1.0.4 is not able to build with this plugin added.
After reading through the README I'm guessing this is based on per IP address it'd be great to be able to base this on per jwt, this wouldn't even need to decode the token just simply use the Authorization header's value instead of an ip.
A runtime error throw while I am using caddy with ratelimit plugin in docker. I have no idea about these errors, and seems that it was ratelimit error destroyed the running caddy.

e.g. You may want to whitelist your own office NAT's IP address/CIDR from the rate limit as presumably your office will hit your own domain far more often than any other legitimate IP.
I actually started to write a PR for this, but it seemed likely that it would likely require a pretty decent refactor to implement.
Hey @xuqingfeng - sorry to open an issue for this, but how can I contact you privately? I want to send you instructions for trying the new build server so we can get it loaded up with your plugin before launching it.
First, thanks for this nice piece of code, I'm adapting it now for one of my use cases but I'm hitting an issue.
It seems that requests are being consumed twice as fast because of this line here:
https://github.com/xuqingfeng/caddy-rate-limit/blob/master/ratelimit.go#L81
From what the docs of "golang.org/x/time/rate" say, calling Reserve() will consume a token, so RetryAfter() should only be called if the request isn't allowed from what I can tell.
Let me know if you want a PR or you'll fix that on your side.
Cheers!
It would be nice to use prometheus to measure how many requests are being rate limited.
I tried to use the ratelimit in Caddy 0.9.5. caddy -plugins says "http.ratelimit" is included.
My conf is the following:
my.webserver.dev:80 {
ratelimit /assets/uikit/vendor/jquery.js 1 1 minute
root /var/www/my.webserver.dev/
fastcgi / /run/php/php7.0-fpm.sock php {
env CI_ENV development
}
log /var/log/caddy/access.log
errors /var/log/caddy/error.log
rewrite / {
ext !.png !.css !.js !.otf !.ttf !.woff !.woff2 !.svg !.ico
to /index.php
}
}
Using ab -n 30 -c 5 http://my.webserver.dev/assets/uikit/vendor/jquery.js
or using curl with a simple bash while loop always returns HTTP 200. The ratelimit is not working.
Logfile says HTTP 200 to every request too.
I tried with curly braces too, but it's not working either.
ratelimit 1 1 minute {
/
/assets
}
What am I doing wrong?
Many thanks for every hint.
