[mapguide-users] MapAgent parameters

[Andy Morsell]

Another cool thing I just discovered along these lines.  If you have
programmatically created a selection object on the server as part of a
session, if you pass the SESSION at the URL, it will draw the selection.  In
this case, since the session is already validated, you do not need to pass
username or password nor are you prompted for it.

Hey,  what do you know...  

I tried adding USERNAME=Anonymous to the request and it worked (because the
password is blank).  I then tried adding USERNAME=Administrator and it
prompted for authentication.  I then tried adding
PASSWORD=mysupersecretpassword to the request and this bypassed
authentication.

I had tried this earlier, but guessed USER instead of USERNAME...

Thanks James,

I had thought about that, but passing authentication info in the link is so
broken (especially in Internet Explorer:
http://support.microsoft.com/kb/834489) that it's not really useful.
This is just a "nice-to-have" until I get to the point of redeveloping my
reports in asp.net or php.  I could see it being useful for providing access
to map images on sites that do not have one of the supported languages
installed though.

You can do this by embedding the user credentials in the URL, like this:

<URL:
http://UserID:Password@localhost/mapguide/mapagent/mapagent.fcgi?...  
>. However, some browsers block this or prompt the user with a
confirmation dialog before submitting the request to the server, so it may
still not do exactly what you'd hoped for.
