[Bug 145065] Re: [needs-packaging] libapache2-mod-limitipconn

[David Jao]

Obviously the previous comment is very old, but I'm afraid it is based
on a misunderstanding of the respective feature sets of mod_limitipconn
and mod_bw.

mod_bw allows you to specify a collection of IP addresses, and a total
aggregate limit on the number of connections allowed from that
collection of addresses. For example, you can say "Serve no more than
five simultaneous connections to the entire 192.168.2.0/24 address
block."

mod_limitipconn by contrast allows you to specify an upper limit on the
number of simultaneous connections that an arbitrary client IP address
is allowed to open. With mod_limitipconn you can say "Serve no more than
two simultaneous connections to any single IP address."

As far as I know there is NO way to duplicate the functionality of
mod_limitipconn in mod_bw, short of enumerating each of the 2^32
possible IP addresses in your apache config file and configuring a
connection limit for each address. If there was such a way, I wouldn't
have written mod_limitipconn, because I tried for a long time to get
mod_bw to do what I wanted.
