Due to security concerns mainly stemming from malicious code modifying the cache, Java Plugin
     deployers and users sometimes prefer to set "no-cache". Meaning the files are transferred from
     the remote system directly to the requesting module. This feature is desirable for Java WebStart
     as well.

We would like to have no-cache support in the common download engine, so it can be used by both JWS and JPI. This also includes the support of the no-cache directive in the http request header.
