I've discovered that the jquery-1.3.2.min.js file gets truncated when served through an Apache reverse proxy setup, most likely because of a lack of newlines, particularly at the end of the file.

My Apache reverse proxy setup looks like this:

<Location /app>
   RequestHeader set X-PROXYPATH /app
   ProxyPass http://internal.domain
   ProxyPassReverse http://internal.domain
</Location>

When I access http://internal.domain/jquery-1.3.2.min.js I get the entire file, but when I access http://external.domain/app/jquery-1.3.2.min.js the file is truncated around the Sizzle CSS comment.

The request header doesn't impact the way the jquery.js file is served, but it's necessary for my application, and is the reason for using a Location block instead of the more common two-argument form of the ProxyPass settings.

Attached is jquery.test.js, which is jquery-1.3.2.min.js with a newline after almost every ; character. (I had to remove the newlines from ; that appear within strings.) This file does NOT get truncated when served through an Apache reverse proxy.
