NimbostratusiRules for 403 forbidden error
Is it possible to create an iRule to remove a specific post request header information to avoid the 403 forbidden error that is generated from an Oracle Apex application?
For example the Origin information below triggers a 403 forbidden message when accessing the application using Edge, Chrome, or FireFox.
I would like to create an iRule to remove the Origin information from the header.
Thanks!

Hi RichardDumag,
You can customize http profile for erase a request header.
Local Traffic ›› Profiles : Services : HTTP ›› http-profile ›› Request Header Erase
Request Header Erase: Indicates the name of an HTTP request header that the BIG-IP system removes from the client request. Only one header can be removed per pool, unless you are using LTM Policies or iRules.
iRule:
when HTTP_REQUEST { HTTP::header remove "Origin" }uri based:
when HTTP_REQUEST { if { [string tolower [HTTP::uri]] equals "/apex_extprd/wwv_flow.ajax" } { HTTP::header remove "Origin" } }
