[Mapserver-users] Retrieving Cached Query, Attempt to modify in URL

[Fawcett, David]

I am trying to pull up a map of a cached query and display it as an image.  

I am able to create the image and display it using the below URL, but what I would really like to do is zoom in on the selected point.  Is it possible to do this using CGI parameters in the URL, or is the extent already set by the query?  

I have tried to add '&zoom=8' to the URL, but this doesn't change the resulting image.  

Would an alternate method be to set mapext to shape and buffer the point out a certain distance?   


<img src=http://127.0.0.1/cgi-bin/ms4/mapserv.exe?map=c%3A%5CApache%2Fhtdocs%2FFac_CF%5Callfac.map&queryfile=c:\apache\htdocs\tmp\allfac10638106372280.qy&layer=facilities&layer=basemap&mode=map&zoom=8&size=200+200">

Thanks, 

David.
