[Geoprisma-dev] Initial page load generate multiple WMS request, one with bad params

[Stephen Woodbridge]

Hi,

I was checking the apache logs while running the above url and on inital 
load of the page I am getting three WMS requests.

http://imaptools.com:8080/project/myproj2/

1) has a bogus image size (WIDTH=5000&HEIGHT=775) and fails because it 
exceeds the default image max size which I think it 2000 in mapserver. 
But if it succeeded this would be bad from a performance point of view 
and tie up a lot of memory and resource computing the image.

2) the next request appears to be at the maximum extents extents of the 
world but not those defined in the map widget extents, but with the 
correct viewport what I'm guessing is the correct viewport size of 
610x610 although I'm not sure how it cam up with that number unless by 
some random chance that the browser geometry just happened to make it 
square.

3) the final image you see after the browser is done loading. This third 
request might be because I added a map.setcenter() call to the template.

If this sounds like a bug, let me know and I will write a ticket for it.
