HTTP:get_session_id()

FortiADC will assign each session a unique ID and allow the user to get this unique ID through this function.

With this unique ID, the user can use Lua scripts to capture request headers, store them into a global variable indexed by this unique ID, and then index a global variable using this unique ID to extract its own request header information in the HTTP request event.

Syntax

HTTP:get_session_id();

Arguments

N/A

Events
