[Zope] Get browser information from HTTP_USER_AGENT..

[Tino Wildenhain]

Hi Pattreeya,

First of all, DONT USE USERAGENT header for anything but informal.
You simply cant depend on that because its free form. Much hassle
these days came from people who didnt understand that. Thats why all
browsers call themself "Mozilla"...

Best way to get "informal" things from the browsers is a simple dtml-page:

<dtml-var REQUEST>

Try it with different User-Agents at will and you will see.
Always a goot thing [tm] would be a in depth knowledge of the
http-protocol as defined in rfc2616 (www.faqs.org)
