Hi All,
In thredds.servlet.ServletUtil.java, line 607:
res.addHeader("Content-Length", Long.toString(contentLength));
The above line is not setting up "Content-Length" correctly for HTTP Head
Request in Tomcat.
As the current implementation in Tomcat, using doGet method to handle HTTP Head
request will be resulted in a NoBodyResponse to be returned.
The NoBodyResponse only accepts response.setContentLength method, otherwise, it
always sets the Content-Length to 0.
Suggested fix is to override doHead() in thredds.servlet.FileServerServlet.java
and make it as a delegator to doGet() method.
Thanks,

Hi Ming Fu,
Thanks for reporting this problem. What version of Tomcat are you running?
