Nimbostratusirule: root domain (only) non-www to www redirect
I have a series of websites that need a non-www to www redirect, bu I still need to support direct subdomains without a redirect.
Example:
- http://abc.com redirects to http://www.abc.com
- http://bank.abc.com does not redirect and stays at http://bank.abc.com
Assume:
- I have a bunch of domains here and don't want write a conditional statement by domain, it's too brittle
- I have several subdomains to support and would prefer not to conditionally address each, but can if necessary
- I need to do http and https
A simple irule that handles 1, but not 2, http only:
when HTTP_REQUEST {
if { ! ([HTTP::host] starts_with "www.") } {
HTTP::redirect http://www.[HTTP::host][HTTP::uri]
}
}
What's an efficient way to say "redirect root domains only" ?

Hi, fo a specific domain irule, you can use:
when HTTP_REQUEST { if { ([HTTP::host] eq "abc.com")}{ HTTP::redirect .[HTTP::host][HTTP::uri] } }
For global domain irule, you might need a regex, maybe something like this:
when HTTP_REQUEST { if { ([HTTP::host] eq "^[^.]+$.com") } { HTTP::redirect .[HTTP::host][HTTP::uri] } }
onlineopsThat rule will work for the TLD (Top Level Domains) .com - and again, if I don't want to get specific about doing "OR" for all the possible TLDs, I think this works, regardless of top level domain:
when HTTP_REQUEST { if { ([HTTP::host] matches_regex {^[a-zA-Z0-9]+\.[a-zA-Z]{2,4}$}) } { HTTP::redirect http://www.[HTTP::host][HTTP::uri] } } when HTTP_REQUEST { if { ([HTTP::host] matches_regex {^[a-zA-Z0-9]+\.[a-zA-Z]{2,4}$}) } { HTTP::redirect https://www.[HTTP::host][HTTP::uri] } }
