           Summary: SSI does not correctly process HEAD request
           Product: Tomcat 5
           Version: 5.5.7
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Servlets:SSI
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: i.tetko@gsf.de
                CC: i.tetko@gsf.de


Hello,

I think there is a small bug in Tomcat 5.0 and 5.5 (at least I could see it already with many versions of 
Tomcat).

I use SSI 
          org.apache.catalina.ssi.SSIServlet

and

     <param-name>isVirtualWebappRelative</param-name>
          <param-value>1</param-value>


All my pages (*.html) are processed by the SSI
        <url-pattern>*.html</url-pattern>

If there is a normal GET request, SSI compiles a page and everything is just OK.

However, for  the HEAD request to the same page (there is no need to compile the page) the SSI still 
tries to do it and generates a number of exceptions (see enclosed).

This error is not critical but overloads my catalina.out file. I do not think that it is difficult to fix it.

I already reported this error to tomcat-dev, but decided to create a formal "bug" report at ASF Bugzilla 
to see if it was already fixed or not. This is not a big error, but it is annoying.

Thanks!

With the best regards,
Igor Tetko
