Hi, Mirrys
I personally can not see a security-hole at the first view ...
Stuff in the global server-variable should only be set by the
webserver and therefore it should be kind-of save (depending on the
quality of the configuration of the webserver ;))
That was also the main reason why I would do a validation-check for this.
Talking about a script-crash ... I don't know ... I just found this
line in a comment for the function gethostbyaddress()
