[Mapserver-users] converting to perl

I will be more specific.  I currently have a mapserver application up on a 
local network.  My eventual goal is to integrate mapserver into some of our 
backend database processing applications.  Initially I am just looking to be 
able to run some perl code of a user of the mapserver queries on a layer.  
What I would like to do is to use the layer information to issue a query to a 
backend database which would pull up service information for hydrants if the 
user clicks on the hydrant.  

The way that I am handling this currently is to have an html page called by 
the query on the layer like so:

<tr><td>[ID]</td><td>[NUMBER]</td><td>[NEWFIELD1]</td>
<td>[NAME]</td><td>Click <a 
href=http://172.16.40.17/cgi-bin/publichydrants/resultshydrant.cgi?sort=none&hydrantname=[NAME]>
Here</a> for data on this hydrant<td></tr>

Here is the reference in the mcse.map file.

LAYER
  NAME hydrants
  TYPE POINT
  MAXSCALE 300000
  STATUS DEFAULT
  DATA hydrants

  CLASS
    NAME "Hydrants"
    TEMPLATE "hydrants.html"
    COLOR 255 0 0
    SYMBOL 'circle'
    SIZE 7
  END

What this method does is if the user queries a hydrants feature they get a 
page that says clieck here for data on this hydrant.  If the user then clicks 
on the link sends the hydrantname to a perl script that queries the database.

What I would prefer to do is to have the query to directly to the perl script 
and not even bring up the intermediate page.

Is this possible?
