This is nothing new... I put up a page sometime around Nov'99 for people who wanted to check out their user agent string. Until a few weeks ago (when my ISP began blocking incoming requests to port 80), it continued to reside on my machine. Since nobody can get it here any more, I've moved it for availability purposes to http://twovoyagers.com/cgi-bin/greet.cgi You can find out about some of the more common CGI environment variables at http://thelinuxservers.com/support/env.htm - Steve
