NimbostratusHTTP header insert rewrites header variable.
I am trying to insert an HTTP header variable with the following iRule:
when ACCESS_ACL_ALLOWED {
HTTP::header insert WL-Proxy-Client-Cert {Access::session data get "session.ssl.cert.whole"]
}
Using a test application to read the header, F5 keeps formatting the variable as "HTTP_WL_Proxy_Client_Cert". Our application won't work with the variable formatted this way, so is there any way to make sure it is formatted exactly as entered in the iRule?
Always use HTTP::header replace instead of HTTP::header insert because it prevents the client pc from putting a malicious value in the original request.
Try putting quotes around the header name. TCL usually is good about guessing that stuff but maybe it's not guessing in the desired way here.
h00ver_290951I changed it to replace and tried with both quotes and no quotes. I still get the same result. Could the receiving server be manipulating the header as well?
Could you paste your irule exactly as it appears in the GUI?
I just noticed in your example above you've got a curly brace and a square brace in a strange area.
