Thanks everybody answering so fast but maybe I didn't explain
so good. All the solutions are concerning the asp file and this is
not my idea, xsl getting values from the querystring was the one.

NOT querystring -> asp -> xsl JUST querystring -> xsl
or better explained:

    querystring (which asp + parameters for the xsl)
           |
     --------------
    |              |
 asp           xsl -----> html
    |              |
    --xml-- + --

thanks again
