iRule Help - if specific URL, redirect, else display a maintenance page

Question

Hello! I currently have a working maintenance page, however the customer wants it if you go to a specific URL, you get redirected, else you get the page. Currently, I have been doing redirects for a bunch of URL's in the following way...when HTTP_REQUEST {
	set httppath [string tolower [HTTP::host][HTTP::uri]]
	switch -glob $httppath {
		"*example.com*" {
			HTTP::redirect https://[string map {"example" "example.new.com"} $httppath] }
} 
}
}
That irule has been working and have no issues. However, now we are trying to introduce a maintenance page. They want it to be where if you go to a specific site, you redirect, else everything hits the page. I've tried adding the following, but get syntax errors...when HTTP_REQUEST {
	if {set httppath [string tolower [HTTP::host][HTTP::uri]]
	switch -glob $httppath {
		"*example.com*" {
			HTTP::redirect https://[string map {"example" "example.new.com"} $httppath] }
else {
  {HTTP::respond 200 content [ifile get "page.html"] }

}
  }
I've tried a few other iterations, however i'm stumped at this point and looking for help.

when HTTP_REQUEST {
    switch -glob -- [string tolower [HTTP::host][HTTP::uri]] {
        "*example.com*" { HTTP::redirect https://example.new.com[HTTP::uri] }
         default { HTTP::respond 200 content [ifile get "page.html"] }
      }
  }
