Find out your browser's name and version and your OS version from an CGI script is simple : you just have to print some variables from a shell script. For exemple, try this script : essai.cgi | #!/bin/sh | echo Content-type: text/plain | echo | echo CGI/1.0 test script report: | echo | echo argc is $#. argv is "$*". | echo | echo SERVER_SOFTWARE = $SERVER_SOFTWARE | echo SERVER_NAME = $SERVER_NAME | echo GATEWAY_INTERFACE = $GATEWAY_INTERFACE | echo SERVER_PROTOCOL = $SERVER_PROTOCOL | echo SERVER_PORT = $SERVER_PORT | echo REQUEST_METHOD = $REQUEST_METHOD | echo HTTP_ACCEPT = "$HTTP_ACCEPT" | echo PATH_INFO = $PATH_INFO | echo PATH_TRANSLATED = $PATH_TRANSLATED | echo SCRIPT_NAME = $SCRIPT_NAME | echo QUERY_STRING = $QUERY_STRING | echo REMOTE_HOST = $REMOTE_HOST | echo REMOTE_ADDR = $REMOTE_ADDR | echo REMOTE_USER = $REMOTE_USER | echo CONTENT_TYPE = $CONTENT_TYPE | echo CONTENT_LENGTH = $CONTENT_LENGTH The web is not anonymous. You can try something like http://www.anonymizer.com/open.html if you want to surf hidden.
