apache - Pass OS values to extJS app -

how can access external system values within extjs application? 1 of main reasons need instead of doing authentication extjs application, using apache provide protected directories on server, want able pass of information user application, once authenticated , app opened. far easier use ldap authentication in manner...

pass values through:

apache → backend app → generated html → frontend app (ext js)

your backend application, whatever technology built on, see authentication information apache in environment variables. actual variable names depend on setup. googlable as:

apache auth user environment variable <your_backend_technology> 

then, information obtained apache need inserted in html javascript/json bit this:

<script type="text/javascript">     var auth_info = {         "username": "john smith"         // other information     }; </script> 

note needs inserted before ext js code.

finally, in ext js app, access info global variable:

auth_info.username
