Tomcat does not cache output of a servlet. By definition the output of a
servlet is dynamic and as such has no reason to be cached. The image is
probably cached somewhere else...

Hi,
I am using Tomcat 5.5.17 with Sun JDK 5.0 Update 7 on CentOS 4.3. I
have a servlet, namely
left out setDateHeader
response.setDateHeader(Expires, 1);
response.setHeader(Pragma, no-cache);
response.setHeader(Cache-Control, no-cache);
Not much to recommend until we see the code which does the conversion (assuming
JPG to PNG)
Anyone else ?

Hey John,
Tomcat does not do any caching. Try adding these HTTP headers:
response.addHeader(Pragma,no-cache); // HTTP/1.0
response.addHeader(Cache-control,no-cache, no-store); // HTTP/1.1
That's the official way. However, due to an IE4-IE6 bug, you might want to
replace the second one by:
Hi
If all else fails, try to add a timestamp variable to the link. By
dynamically adding a unique timestamp like
http://foo.com/document.jsp?time=[timestamp] the page will not be
cached.

The WTP plugin for eclipse copies what is in META-INF/context.xml and writes
it into CATALINA_BASE/conf/server.xml.
