The web browser will send info about itself in the User-Agent line. A browser might send you something like: `GET / HTTP/1.0 Connection: Keep-Alive User-Agent: Mozilla/4.72 [en] (X11; U; Linux 2.2.16 i686) Host: localhost:1101 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png +, / Accept-Encoding: gzip Accept-Language: en Accept-Charset: iso-8859-1,*,utf-8` [download]	[reply] [d/l]

I'm not clear on what you mean by "called from the html page using a image reference", and this may not apply since you're using "a simple socket server", but I use the following environment variables from `CGI.pm`. `$ENV{'REMOTE_HOST'} $ENV{'REMOTE_ADDR'} $ENV{'HTTP_USER_AGENT'}` [download] If this is what you're looking for, more info can be found at http://stein.cshl.org/WWW/software/CGI/. No mater how you extract this info, it's trivially spoofed, so you shouldn't base any security on what browsers tell you about themselves. cheers, ybiC	[reply] [d/l]

Or, slap this in a page and see the entire environment that is passed in the request: `use Env; print "<!--\n"; foreach $parameter ( sort keys %ENV ) { print "$parameter is: $ENV{$parameter}\n"; }` [download]	[reply] [d/l]

Check out Environmental Variables for an program that lists the env. variables.	[reply]

yes, user-agent line, a web client will send a series of plain text lines that tell the server what types of files it accepts, what domain name its looking for (for ipless hosts), and included within that data is a line that is simply called the "User-Agent" line. Everything after the User-Agent: is the type of browser and operating system they are using.	[reply]
