I'm kind of curious why you are using Apache httpd if you just want a single connection to be available. Anyone can write a single-connection HTTP service in about two pages of higher-level source code (e.g. Python, Java, C#, maybe even Perl). This is a bit like using a Saturn V rocket to launch a weather balloon. For a single connection, make sure that you disable keepalive -- or at least set the keep alive timeout to something small, like 1 second. Otherwise, you'll DOS yourself quite easily. I would also set the TCP backlog to something small. Maybe as little as 1 (or 0, if that doesn't actually mean "backlog until we run out of memory"). - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlbHMyAACgkQ9CaO5/Lv0PCRigCfTmzndG7agsZ9EmwM0sJTLMV9 ccAAoLD/DvkLbrsZhNnQMRXDQGRU+KOR =NC4e -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
