ok, i've been fighting with my http server for a looong time now. it works perfectly fine when i use a proxy server, and doesn't when i don't. i couldn't figure out for the life of me why, so finally i use a packet sniffer and found the only difference. the one with the proxy adds a crlf at the end. i don't know if it is against the http rfc to do this (though i should know, i've read the thing over and over now..), but i don't think any browser i tested successfully sent a crlf after the post data.

here is the output in mirc

without proxy:

is there any way around this? i have thought and thought of ways to force internet explorer add another line (one that i wouldn't use or something) at the end... or maybe even force mirc into reading that last line no matter how much it doesn't want to, but i can't figure out how

.

i also read the help file, and couldn't find any documentation about this, so any help you could provide would be very much so appreciated.

well, that's my bug report... i've tested several times, and the results are 100% the same... do not deviate at all.

thanks

Collective Hoopy frood C Joined: Dec 2002 Posts: 3,138 London, UK	Are you using /sockread with a %variable and no -f switch (or binvars with just the -n switch)? If you are, then that's why. From the mIRC helpfile: /sockread [-fn] [numbytes] <%var\|&binvar> If you specify a %var variable, a line of text ending with a Carriage Return/LineFeed is read into %var. The $crlf are stripped off (this may result in %var being $null if the line only consisted of $crlf). If you specify the -f switch with a %var variable, this forces mIRC to fill the %var variable with whatever text is in the receive buffer, even if it doesn't end in a $crlf. The -n switch allows you to read a $crlf terminated line into a &binvar. If the incoming line does not contain a $crlf, no bytes will be read into &binvar, unless you specify the -f switch, which forces the read (same as when reading into %vars). You might like to try binvars, or the -f switch. Last edited by Collective; 18/01/04 01:28 AM.

You should keep reading until $sockbr (bytes read) is set to zero. This is far faster than letting mIRC re-trigger the event. If your script doesn't read the whole buffer, the on sockread event is re-triggered if: a) you were reading into a &binvar. b) you were reading into a %var and there is still a $crlf terminated line in the buffer waiting to be read.

Unfortunately, because 75%+ of people that post here do not actually read the help file, or browse the Forums in search of threads that cover the topic, we automatically assume that the person hasn't read it, or has missed something. Remember that we do give up our free time to be here and help others in any way that we can, and all help should be appreciated, without us being called smartasses etc. I'm glad you got your problem sorted though Happy chatting!

"The only foolish question is that which is not ask by a fool"
