I'm trying to insert google analytics code into an app by using the
directions at http://wiki.nginx.org/HttpSubModule.

In so doing, I first tried to set a variable as follows:

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

to get the text into the variable but of course that generates an error:

nginx: [emerg] invalid number of arguments in "set" directive in
/usr/local/etc/nginx/sites-enabled/mysite.com:12.

Searching Google I found a few threads about trying to place the
contents of a file into a variable but there didn't seem to be a way.

I also tried simply adding the text into the "sub_filter" line but that
also threw an error:

nginx: [emerg] unexpected "_" in
/usr/local/etc/nginx/sites-enabled/mysite.com:16

Using the following:

server {
...

sub_filter </head>
'</head><script language="javascript" src=/home/jim/ga.js></script>';
sub_filter_once on;

...
}

resulted in the following:

jim$ curl http://mysite.com/somepage

....
</head><script language="javascript" src=/home/jim/ga.js></script>
....

Putting the path in quotes changed nothing other than that portion being
in quotes.

Obviously I'm doing something wrong. Any help would be appreciated.
