ACE header HTTP_FRONT_END_HTTPS=On

troypennpeterson · ‎02-12-2014

I have a site that is behind an ACE. I can see a HTTP_FRONT_END_HTTPS=On header variable coming thought which appears to indicate the connection to client is secure. Can somebody tell me if this is added by the ACE be default or if it needs to be configured. I see from Wikipedia that it's "non-standard" so that is why I am questioning the reliability for use on other sites behind the ACE without knowing where it's set.

X-Forwarded-Proto^[17]	a de facto standard for identifying the originating protocol of an HTTP request, since a reverse proxy (load balancer) may communicate with a web server using HTTP even if the request to the reverse proxy is HTTPS	X-Forwarded-Proto: https
Front-End-Https^[18]	Non-standard header used by Microsoft applications and load-balancers	Front-End-Https: on

Hi Troy,

If you have the below configuration in ACE then yes it is ACE which is inserting the aforesaid header.

action-list type modify http xxxx
 header insert request FRONT-END-HTTPS header-value On 

 
 You can use it wherever required.
 
 Let me know if you have any questions.
