Google Analytics revisited

[#1]

Following up on this earlier article try using the below TrafficScript code snippet to automatically insert the Google Analytics code on all your webpages.  To use it:

1. Copy the rule onto your Traffic Manager  by first navigating Catalogs -> Rules
2. Scroll down to Create new rule, give the rule a name, and select Use TrafficScript Language.  Click Create Rule to create the rule.
3. Copy and paste the rule below.
4. Change $account to your Google Analytics account number.
5. If you are using multiple domains as described here set $multiple_domains to TRUE and set $tld to your Top Level Domain as specified in your Google Analytics account.
6. Set the rule as a Response Rule in your Virtual Server by navigating to Services -> Virtual Servers -> <your virtual server> -> Rules -> Response Rules and Add rule.

After that you should be good to go.  No need to individually modify your web pages, TrafficScript will take care of it all.

#
# Replace UA-XXXXXXXX-X with your Google Analytics Account Number
#
$account = 'UA-XXXXXXXX-X';

#
# If you are tracking multiple domains, ie yourdomain.com,
# yourdomain.net, etc. then set $mutliple_domains to TRUE and
# replace yourdomain.com with your Top Level Domain as specified
# in your Google Analytics account

#
$multiple_domains = FALSE;
$tld = 'yourdomain.com';

#
# Only modify text/html pages
#

if( !string.startsWith( http.getResponseHeader( "Content-Type" ), "text/html" )) break;

#
# This variable contains the code to be inserted in the web page. Do not modify.
#

$html = "\n<script type=\"text/javascript\"> \n \
  var _gaq = _gaq || []; \n \
  _gaq.push(['_setAccount', " . $account . "]); \n";

if( $multiple_domains == TRUE ) {
  $html .= " _gaq.push(['_setDomainName', " . $tld . "]); \n \
  _gaq.push(['_setAllowLinker', true]); \n";
}

$html .= " _gaq.push(['_trackPageview']); \n \
  (function() { \n \
  var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; \n \
  ga.src=('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; \n \
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); \n \
  })(); \n \
</script>\n";

#
# Insert the code right before the </head> tag in the page
#
$body = http.getResponseBody();
$body = string.replace( $body, "</head>", $html . "</head>");
http.setResponseBody( $body );

I am seeing a syntax error when I copy and paste the provided TrafficScript rule to a Stingray Traffic Manager 8.1r1 virtual appliance.  Any help to fix would be greatly appreciated.

Warning: line 23: Unknown escape sequence '\ '

  $html = "\n<script type=\"text/javascript\"> \n \ 

  ^

Error: line 23: Unterminated string constant

  $html = "\n<script type=\"text/javascript\"> \n \ 

Error: line 24: syntax error, unexpected function

  var _gaq = _gaq || []; \n \

Hi Mike,

Copy and pasting from that text box adds a few extra white spaces at the end of each line.  To fix, just delete the extra white space on the lines it complains about.
