Is there a need for a {(server ...)} markup expression? Would it not
be more fitting to use page variables for things like the user's browser
name or the ip address? And then I would use terms like {$Browser} and
{$IPAddress}. Just a short while ago Pm gave a definition for use of
"browser" in conditional markup. Who would want to use
{(server HTTP_USER_AGENT)} as wiki markup?

So a user who does not read much documentation, or does not memorise
it very well, tries to use {(server browser)} and this does not work.
so he will have to look up the meaning of {(server..)}, and finds
mention of HTTP_USER_AGENT. Then he is supposed to "google" on that
term to get more information?
To help a non-programming user it would be good to have a page
variable {$Browser}, which return a simple browser name, and perhaps
also {$BrowserVersion} to return a simple version info, good enough to
do any conditional switching.
Or are the markup expressions made available a backdoor to introduce
pure PHP, and Apache, terminology? A geek's powertool box in other
words, only for the initiated?
