That's the only way to do it 8^)

This is not a legal URL to pass multiple CGI query
variables use (notice the ampersand):

http://foo:8080/bar?var1=val1&var2=val2

These values get added to the REQUEST object, which
exposes them at the bottom of the namespace stack
(REQUEST is the last place checked for names). So, you
can either directly access them, or access them as
attributes or items of the REQUEST object.

for the above URL, the following lines would work:

<dtml-var name="var1">
&dtml-var1;
<dtml-var expr="REQUEST.var1">
<dtml-var expr="REQUEST['var1']">

The latter two are more explicit and would avoid
namespace collisions.
