Ok, so this just gives a hint as to what a url someone posts does. You can make it personal use or have it msg the chan. I'm working on getting it to work on tinyurls and other compressed addresses....not sure why it doesn't so any help in that department would be much appreciated. I'm thinking to use a separate socket for specific tinyurls

I used Gummo's $between...

eventual update will hopefully work for redirects like tinyurl and other url compression sites...this was more about learning socket and is my first "finished" socket script

on *:text:*http*:#: { 
    var %x $1-
    var %z 1
    while (%z <= $numtok(%x,32)) {
      if (http:// isin $gettok(%x,%z,32)) { /urlcheck $chan $gettok(%x,%z,32) | BREAK }
      /inc %z 1
    }
  }

alias urlcheck {
  unset %url.*
  set %I $ticks
  set $+(%,url.chan.,%I) $1
  set $+(%,url.check.,%I) $replace($2,http://,$null)
  set $+(%,url.host.,%I) $gettok($eval($+(%,url.check.,%I),2),1,47)
  set $+(%,url.get.,%I) $replace($eval($+(%,url.check.,%I),2),$eval($+(%,url.host.,%I),2),$null)
  sockopen $+(remoteurl.,%I) $eval($+(%,url.host.,%I),2) 80
}

on *:SOCKOPEN:remoteurl.*: {
  sockwrite -n $sockname GET $+($chr(47),$($eval($+(%,url.get.,%I),2)))
  sockwrite -n $sockname Host: $($eval($+(%,url.host.,%I),2))
  sockwrite -n $sockname User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 $+ $crlf $+ $crlf
}

on *:SOCKREAD:remoteurl.*: {
  var %r
  sockread %r
  if ($regex(%r,<title>)) {
    ;msg $eval($+(%,url.chan.,%I),2) ' $+ $between(%r,<title>,</title>,1) $+ ' (at ' $+ $eval($+(%,url.host.,%I),2) $+ ') 
    .echo $eval($+(%,url.chan.,%I),2) ' $+ $between(%r,<title>,</title>,1) $+ ' (at ' $+ $eval($+(%,url.host.,%I),2) $+ ') 
  }
}

; Gummo's
alias between { 
  noop $regex($1,/\Q $+ $2 $+ \E(.*?)\Q $+ $3 $+ \E/gi) 
  return $regml($4) 
}
