how to redirect in F5 balancers

A small note:

[HTTP::host] - will return the host header value

[HTTP::host] eq "dns.domain.com" - will return 0 or 1 depending on whether the HTTP host is dns.domain.com or not

[[HTTP::host] eq "dns.domain.com"] - will try to execute 0 or 1 and return a runtime TCL error as 0 or 1 isn't a valid command

Similarly:

[HTTP::uri] - will return the URI (path plus query string)

[HTTP::uri] eq "/" - will return 0 or 1 depending on whether the HTTP URI is / or not

[[HTTP::uri] eq "/"]] - will try to execute 0 or 1 and return a runtime TCL error as 0 or 1 isn't a valid command

You could use this:

    if { [string tolower [HTTP::host]] eq "dns.domain.com" and [HTTP::uri] eq "/"] } {

Or use Joe's preferred syntax:

    if { [string tolower [HTTP::host]][HTTP::uri] eq "dns.domain.com/" } {

F5 needs to release a "Hoolio App" that automatically adjusts your iRule to correct syntax so you don't have to correct mine üòõ
