             Summary: Improvements needed (regarding caching) in the URLTransport* API
                 Key: JBIDE-17148
                 URL: https://issues.jboss.org/browse/JBIDE-17148
             Project: Tools (JBoss Tools)
          Issue Type: Feature Request
    Affects Versions: 4.2.0.Beta1
            Reporter: Fred Bricon
            Assignee: Rob Stryker
             Fix For: 4.2.0.Beta2


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/org.jboss.tools.foundation.core/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 
{quote}
public File getCachedFileForURL(String url, String displayName, int lifespan, IProgressMonitor monitor) 
{quote}

with 
{quote}
public File getCachedFileForURL(String url, String displayName, URLTransportCache transportCache, IProgressMonitor monitor) 
{quote}

Or if you have any better idea, be my guest :-)
