[mapguide-users] Bypassing initial view at startup

[Kenneth Skovhede, GEOGRAF A/S]

Yes, that is the way to go. Although, you PHP page can redirect to the 
ajaxviewer,
so you do not have to fiddle with the iframe src, but just point at the 
startup PHP page.

There are two other options:
1. handle "onload" in javascript and zoom there
2. modify the ajaxviewer to read the new center/scale info

Option number 1 has a drawback, as you will request two initial images.
Option number 2 is going to give you headaches when you upgrade.

I'm not a PHP expert, but I'm sure someone else has the correct code.
Are there any steps that you want explained from the link you provided?
