How Do I Get the Buffer Data??

[Ben Ocean]

Hi;
I'm writing a CGI script. One last thing to figure out. The data is being 
sent to me by a foreign host (around which I frame). They send the data to 
a URL I specify (in my cgi-bin directory) and send the data to a *data 
buffer*. I need to call it from that data buffer. How do I do this?
TIA,
