-From:
-http://www.mail-archive.com/dev@httpd.apache.org/msg37189.html
-
-Hi!
-
-
-Attached is a version of mod_limitipconn.c that works in conjunction with
-mod_cache and httpd-2.2. We've been using this on ftp.acc.umu.se for some
-time now without any unwanted issues.
-
-The main problem with mod_limitipconn-0.22 was that since mod_cache runs as
-a quick handler, mod_limitipconn also must run as a quick handler with all
-those benefits and drawbacks.
-
-Download the tarball from http://dominia.org/djao/limitipconn2.html , extract
-it, and replace mod_limitipconn.c with this version and follow the build
-instructions.
-
-I would really wish that this was made part of httpd, it's really needed when
-running a file-download site due to the scarily large amount of demented
-download manager clients out there.
-
-However, I have not received any response from the original author on the
-matter. From what I have understood of the license it should be OK to merge
-into httpd if you want though, but I think that you guys are way more clued
-in that matter than me.
-
-This is a summary of the changes made:
-* Rewritten to run as a Quick Handler, before mod_cache.
-* Configuration directives are now set per VHost (Directory/Location
- are available after the Quick Handler has been run). This means that
- any <Location> containers has to be deleted in existing configs.
-* Fixed configuration merging, so per-vhost settings use defaults set
- at the server level.
-* By running as a Quick Handler we don't go through the entire lookup
- phase (resolve path, stat file, etc) before we get the possibility
- to block a request. This gives a clear performance enhancement.
-* Made the handler exit as soon as possible, doing the "easy" checks
- first.
-* Don't do subrequest to lookup MIME type if we don't have mime-type
- specific config.
-* Count connections in closing and logging state too, we don't want to
- be DOS'd by clients behind buggy firewalls and so on.
-* Added debug messages for easy debugging.
-* Reduced loglevel from ERR to INFO for reject-logging.
-
-In any case, I hope that this can be of use for others than us.
