[cgiapp] showing "temporary output"

[ademmler]

Hi CCGI::APP List members!

I need some help to do the following:

My steps
1. start web page in runmode1 offering a CGI form
2. submit form and process it
3. display result as runmode2

Because step 2 takes a long time I want to show a "please be patient  
message" in between.

So far I am fine, but how can I change into a new runmmode after  
outputting the HTML page with    "return $template->output();
Or better has some body the right concept for doing this?

Thanks to all
Alexander
