[support] Question about iFrames

[Daniel Carrera]

Hello,

This is an HTML question. I installed the Moodle integration module. It 
puts Moodle inside an <iframe> in a Drupal page. So far so good. The 
problem is when you click on a link inside Moodle (iframe). I always 
thought that clicking on a link inside an iframe would only change the 
contents of the iframe. But this is not what always happens. Some times 
the entire browser page refreshes, taking you out of Drupal, to Moodle, 
and breaking the illusion that Moodle is inside Drupal.

What is especially disconcerting is that this happens on some pages but 
not others. So it creates a weird kind of unpredictability that I'm sure 
will annoy users.

I cannot see any obvious reason why there is a difference. The links 
that produce different results don't look all that different. They are 
all on the same domain, of the form http://foo.org/moodle/<something>.

Does anyone know what can cause this behaviour? I need to understand the 
root cause at the HTML level before I can figure out if there is 
something I can change at either Moodle or Drupal to correct the problem.

Thanks for the help.

Daniel.
