Hi all, 

A couple of months ago, my boss asked me if it was 
possible to display an Internet Access Policy when 
users first launch their browsers without setting the 
"Home" or "Start" page. His thought was that it should

be possible with our current Squid Servers. I searched

the mailing list and noticed the question had been 
asked before but it wasn't possible without some 
coding. I let him know. 


The problem bugged me for ages. I do not know how to 
program in C so writing the necessary code was not an 
option for me. Also what about sites that do not use a

Proxy Server or a server other than Squid. To cut a 
long story short I developed an application in TCL 
that I want to share with the Squid community in an 
effort to give something back and hopefully to help 
others. 


The application is called "HeadsUp" and it can display

an Internet Access Policy or Message of the Day(MOTD) 
to users. Browsers need to be configured to use a PAC 
file and a slight change to any existing PAC file is 
all that is needed. The PAC file directs the browsers 
first request to the server which is running 
"HeadsUp". "HeadsUp" downloads a page which brings up 
a Popup window and causes the browser to reload the 
page again to load the real page. "HeadsUp" is 
available from http://www.freewebs.com/headsup It is 
built on Tclhttpd a webserver in written pure TCL and 
packaged as a Starkit. It runs on Windows, Linux, 
HP-UX, Tru64 and Solaris. 

Easy to install, just copy 2 files to your system and
run. No compiling necessary. To uninstall delete the 2
files!

Enjoy! 


Kind Regards
