There are a few things I'd like to see improved in the URL Transport API, wrt caching.

Currently :

• all files are downloaded and cached under <workspace>/.metadata/.plugins/org.jboss.tools.foundation.core/ECF_REMOTE_CACHE, using a cryptic name
• Cache doesn't survive JVM restart

What I need/expect :

• ability to set custom cache folder
• store files under <cache.folder>/requested.url. eg. : if I request https://foo.bar.org:8080/some/location/file.txt, it'll be stored under <workspace>/.metadata/.plugins/my.plugin/cache/http_foo.bar.org_8080/some/location/file.txt
• restarting the IDE will be able to read the cached file

Currently URLTransportCache is a singleton. We could change that and add the cache location as a constructor argument, have a URLTransportCache.DEFAULT instance, used by URLTransportUtility and probably override

public File getCachedFileForURL(String url, String displayName, int lifespan, IProgressMonitor monitor)

with

public File getCachedFileForURL(String url, String displayName, URLTransportCache transportCache, IProgressMonitor monitor)

Or if you have any better idea, be my guest
