BIG-IP add custom header
F5 BIG-IP LTM VE v11.4.0 on ESXi
I want to add a custom header to my request before rewriting to a backend server :
when HTTP_REQUEST {
HTTP::header insert uri-original [HTTP::uri]

do you assign multiple irules to the virtual server? does action conflict each other?
- my virtual-server is assigned multiple i-rules but i believe a rewrite from an ssl to a non-ssl pool is causing the original-uri i-rule to be invoked twice. however what i find confusing is that elsewhere in the forums i've read that it's possible to add multiple headers with the same name to a request - and yet here adding a header that already exists throws an error
- nitass_89166i do not think the error is caused by adding header name which exists. i think its action does conflict with another.
- could you please elaborate ? no further action is taken with the added header -- it is simply a header that is added server-side for use client-side
