DataScript: avi.http.get_host_tokens

Function	avi.http.get_host_tokens( [start [, end]] )
Description	Retrieve individual host sections, or tokens, from the hostname (aka strings separated by the delimiter ‘.’) when called without arguments. The command provides the flexibility to get a slice of host tokens (see examples below) when start and/or end indices are provided.
Events	HTTP_REQ HTTP_RESP
Parameter	*start* and/or end indices, which allow parsing out section of the host header.
Returns	If no start and end indices are specified, returns a table of all the host tokens. If either start index is specified or both start and end indices are specified, returns a string.
Example	Example host header: http://www.avinetworks.com/a/b/index.htm?avi=true Returns ‘www.avinetworks.com’ `avi.http.get_host_tokens(1)` Returns ‘avinetworks’ `avi.http.get_host_tokens(2,2)` Returns ‘nil’ `avi.http.get_host_tokens(6)` Validate the second and third fields of the hostname are ‘avinetworks.com’. `domain = avi.http.get_host_tokens(2, 3) if domain ~= "avinetworks.com" then avi.http.redirect("new.avinetworks.com") end`
