That will only go so far. Suppose you tell web browsers "no more than
3 connections", then get hit by 30 nearly simultaneous, but separate
clients. Then you still wind up allowing up to 90 connections.

There should be a parameter in your web server's config file to limit
the number of simultaneously active threads or processes. It's been a
long time for me, and you don't mention what brand of server you are
running, but ISTR that Apache has/had such parameters.

(Also, while this is off-topic for comp.lang.python, most people here
are a helpful bunch, and recognizing that it is off-topic, will want
to reply off-list. You don't give them that option with
"invalid@invalid.invalid" as an email address.)
