Redirect between mobile and full domains - dotCMS

## Intelligently send people back and forth between different versions of
## the same page on mobile and full domains depending on
## 1) their devices, 2) whether or not the URL has "?siteversion=full" or ?siteversion=mobile
## and 3) whether cookies have been set by the other two conditions.
##
## Logic flowchart (rough) - http://twitpic.com/6e4woa

## This code makes use of ISAAC's mobile detection plugin:

## Your site domains
#set($fullDomain = "www6.oc.edu")
#set($mobileDomain = "m.oc.edu")

######################  SET VARIABLES DEPENDENT ON CURRENT PAGE ADDRESS

	## Domain
		#set($requestURL = "$request.getRequestURL()")
		## Detect if you're on the mobile domain by analyzing the site URL (does it contain my mobile domain?)
		#set($onMobileDomain = $requestURL.matches("^https?:\/\/($mobileDomain).*"))

		#if($onMobileDomain == true)
			#set($otherVersion = "full")
			#set($currentVersion = "mobile")
			#set($otherDomain = $fullDomain)
		#else
			#set($otherVersion = "mobile")
			#set($currentVersion = "full")
			#set($otherDomain = $mobileDomain)
		#end

	## Page URL
		## Some kung fu to find the page address if we're in URL mapped content
		#if($URLMapContent)
			#set($currentURLMapContent = $dotcontent.find($URLMapContent.identifier))
			#set($pageUri = $currentURLMapContent.getUrlMap())
		#else
			#set($pageUri = $request.getRequestURI())
		#end

	## QUERY STRING
		#set($queryString = $request.getQueryString())

		## Remove "siteversion" variable from query string before passing to another site (to prevent repetition)
		#set($queryString = $queryString.replaceAll("(siteversion=[a-zA-Z]*&?)|(&?siteversion=[a-zA-Z]*)$",""))
		#if($UtilMethods.isSet($queryString))
			#set($queryString = "?$queryString") ## Add the question mark
		#end

		## If there's already a query string, add siteversion onto it, otherwise make it just siteversion
		#if($UtilMethods.isSet($queryString))
			#set($siteversionquery = "&siteversion=${otherVersion}")
		#else
			#set($siteversionquery = "?siteversion=${otherVersion}")
		#end


	#set($otherUrl = "http://${otherDomain}${pageUri}$!{queryString}") ## The mirror of this page on the other server
	#set($otherUrlwSiteversion = "$otherUrl$!{siteversionquery}") ## The mirror of this page, with siteversion=??? to set a cookie there



######################  MACROS

	#macro(redirectme $url)
		## Keep browsers from remembering this redirect in case people change their mind on the site version
		$response.setHeader("Pragma", "no-cache")
		$response.setHeader("Cache-Control","no-store")

		## Send me somewhere
		$response.sendRedirect($url)
	#end

	#macro(siteversioncookie $cookievalue)
		## Get a date 30 days from now to feed to cookie
		#set($now = $date.format('MM/dd/yyyy HH:mm:ss', $date.getDate()))
		#set($now30= $date.getDate().getTime() + 2592000000) ## Add 30 days
		#set($now30 = $date.format('E, dd-MMM-yyyy HH:mm:ss zzz', $now30))

		## Set the cookie
		$response.setHeader("Set-Cookie","siteversion=$cookievalue;expires=$!{now30};path=/;domain=oc.edu")
