greetings
What is the best way to check if a website is online and return an error if it is not?
Thanks

I just wrote up a quick script, Just add it to the remotes section of mIRC scripts editor. alias checkwebsite {
if (!$1) {
echo -at You need to specify a website!!!
}
else {
var %sn checkwebsite. $+ $md5($ticks $+ $r(1111,9999))
sockopen %sn $1 $iif($2,$ifmatch,80)
sockmark %sn $1 $iif($2,$ifmatch,80)
}
}
on 1:sockopen:checkwebsite.*:{
if ($sockerr) {
var %cw.msg There was an error connecting to:
}
else {
var %cw.msg Successfully connected to:
}
echo -at * %cw.msg $replace($sock($sockname).mark,$chr(32),$+($chr(32),on port,$chr(32))) $iif($sockerr,$+($chr(40),$sock($sockname).wsmsg,$chr(41)))
if ($sock($sockname)) {
sockclose $ifmatch
}
}Usage: /checkwebsite <URL/IP> [PORT] So to check hotmail website, type "/checkwebsite hotmail.com" But if you need to check hotmail secure, then try "/checkwebsite hotmail.com 443" or to check an IRC server, try /checkwebsite <servername> 6667 I think you should get it! Hope this helps.

Couldn't you also /dns it, and if no response, then, it's down?

No. DNS records are stored on a nameserver, which is very rarely the same machine that hosts the actual website. Even if it was, the fact that DNS is responding is no guarantee that a specific webpage is also running correctly.
Spelling mistakes, grammatical errors, and stupid comments are intentional.

alias http.status {
.comopen xml msxml2.xmlhttp
noop $com(xml,open,1,bstr,get,bstr,http:// $+ $1,bool,-1)
var %a = User-Agent:Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 1.1.4322) : $&

Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/x-silverlight, */* $&
,%i = 1
tokenize 58 %a
while ($(,$ $+ %i)) {
noop $com(xml,setRequestHeader,3,bstr,$v1,bstr,$gettok(%a,$calc(%i +1),32))
inc %i 2
}
noop $com(xml,send,1) $com(xml,status,2)
var %x $com(xml).result
.comclose xml
return %x
:error
if ($comerr) echo -geca info * $!http.status : $error $com(xml).errorText
reseterror
return 0
}
Returns 200 if website loaded OK (HTTP Value for OK) and otherwise returns the HTTP Code (i.e 404 and 500) or the WinSock Error Code. usage:
if ($http.status(www.mirc.com) == 200) sockopen ...
else echo -a cannot open mirc.com website is down!

No probs, Glad to help  @MPDreamz: Using HTTP status codes isnt good for detecting if a website is online. * If I have forbidden a user from viewing /index.php without logging in first, I would return 403 forbidden. * If the site is SSL, Plain text of the status codes wouldnt be returned (allthough the object may allow it). * Because a page is missing (404) dosnt mean the whole website is down. Im sure you get the point.

Thats because i assumed he wanted to check if he could connect properly. You could check for WinSock Errors directly by checking
if ($http.status(www.mirc.com) > 600) echo -a site down or does not exist.
Your right about username and password though, so i thought id include it
alias http.status {
var %p http://,%u $2,%w $3,%a Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; .NET CLR 1.1.4322), %x
if ($prop) %p = https://
.comopen xml msxml2.xmlhttp
if ($0 < 2) echo -a $com(xml,open,1,bstr,head,bstr,%p $+ $1,bool,-1)
else noop $com(xml,open,1,bstr,head,bstr,%p $+ $1,bool,-1,bstr,%u,bstr,%w)
noop $com(xml,setRequestHeader,3,bstr,User-Agent,bstr,%a) $com(xml,send,1) $com(xml,status,2)
%x = $com(xml).result
.comclose xml
return %x
:error
echo -geca info * $!http.status : $error $com(xml).errorText
if ($com(xml)) .comclose xml
reseterror
return s
}
usage: $http.status(URL[,username[,password]])[.secure]
