So does phttpd for regular files. I don't know which version was the first one. It won't keep the connection open if it calls CGI program, even if the CGI sends Content-Length. You can't trust those things. :) > As far as I'm aware, current versions of Netscape Navigator and MSIE > (to name two popular web browsers) both support persistent connections > with the Keep-Alive methods. Netscape 2.0 has a nasty bug in handling keep-alive connections. It will probably receive the HTML page and then just hang while trying to receive the images. Apache (don't know which version) can be told not to use Keep-Alive connections with particular client. Note that MSIE 3.0x sends "Mozilla/2.0" in user-agent header and blocking NSN 2.0 would also block MSIE 3.0x which does not have that bug, as far as I know. But... Microsoft asked for it. :) -- They work 24 hours a day and 256 days a year -- root@fly.cc.fer.hr dave@srce.hr dave@fly.cc.fer.hr
