           Summary: Tomcat insert header info into javascript code
           Product: Tomcat 5
           Version: Unknown
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Webapps:Examples
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: jizu@osa.sunysb.edu


I am using Tomcat 5.5.12, JDK-1_5_0_05 on XP professional. I copied javascript
file ftiens4.js under webapps/myPractice, then typed URL
http://localhost:8080/myPractice/ftiens4.js

I was expecting the original javascript code without any change. To my suprise,
I saw following code appeared near the end of the screen.

      brHTTP/1.1 200 OK
Server: Apache-Coyote/1.1
ETag: W/"33879-1130270899484"
Last-Modified: Tue, 25 Oct 2005 20:08:19 GMT
Content-Type: text/javascript
Content-Length: 33879
Date: Tue, 25 Oct 2005 20:35:18 GMT

I am attaching the source code of ftiens4.js below. Hope you can repeat the
strange phenomena.
