[LON-CAPA-dev] Apache handler question

Quoting Mark Lucas <lucas@lucas.phy.ohiou.edu>:

Sure.

It does multiple things

- Checks the Cookie
- loads the seeson envirnoment
- Checks if the user has access
- and is allowed to view it
- logs access
- fires up the login page if needed

And

- parses POST parameters into the $ENV{'form.*'} variables

Modify lonacc, move lines 90 - 149 on lonacc.pm into loncommon.pm

Call it something like 'parse_post_form'

Have lonacc.pm call it, and add a call to it in your handler or

>  - is there a DIFFERENT access handler that I need? Or need to write?

make a simple access hangled that only calls to above new function

get_unprocessed_cgi

only handles parameters posted in the URL

I.E.
http://machine.com/adm/handler?myvalue=true&myothervalue=false

And it only will pull in calues that it is told to,

I.E, with the above URL and a call to 
&Apache::loncoommon::get_unprocessed_cgi($ENV{'QUERY_STRING'},['myvalue']);

Will set $ENV{'form.myvalue'} but ignore the myothervalue
