Nice write-up but it's a non-standard and maintenance-prone "solution". Maybe people not like you (;-p) should choose a combination of iptables rate limiting, webserver "BrowserMatch" and mod_security filtering instead?..
Great! Describe your implementation "step-by-step" in a detailed write-up and avoid hand-waving and we'll have a look
PS (Edit): mod_security can be a very big performance killer on a very busy web server.... intercepting every URL and trying to match each one against a long list of rules can kill performance.

I like it, especially using cut and sort versus awk. I always use wget, so I should look into using lynx from time-to-time!

Hello,
Would this be an acceptable way of creating a non-blocking pipe.
Basically I want to create kind of a server client arch.
This code would be in the server, and I don't want to have to wait for
clients to read before moving on to the next client. One problem I
can see is if... (4 Replies)
