Modification of HTTP Header in AJAX?

Hello All,

I use dhtmlxscheduler for a calendar service.
I have to insert a new field to the HTTP header of the AJAX request toward the server with session id for authentication purposes.

My question is:
How to modify HTTP Header before sending the AJAX request?

Thank you,


The only way is code modification.


You can locate the next line

and add any custom headers after it
