[Aslak Knutsen (JIRA)]

    [ https://issues.jboss.org/browse/SHRINKWRAP-496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13135362#comment-13135362 ] 

Aslak Knutsen commented on SHRINKWRAP-496:
------------------------------------------

It could technically be implemented as a Handler, but I don't think we have any way to globally register a Handler. Or register it dynamically for that matter.

{code}
archive.addHandlers(new ArchiveEventHandler() {
  public void handle(ArchiveEvent event) {
    if(event.getAsset() instanceOf URLAsset) {
       // lookup cache / cache content
       event.setHandledAsset(new FIleAsset(cachedFile));
    }
  }
})
{code}

> In ShrinkWrap UrlAsset downloaded an asset from a URL, which can be external and then it creates the Archive element with that info. The problem is that sometimes you might want to download a big file (2MB) to put inside an Archive, and this means that for each test class that you execute you end up by downloading this file.
> A possible solution could be create a CacheUrlAsset that downloads the content and stores it in {java.io.tmp}/shrinkwrap so in successive calls before downloading the file again, it can take it directly from cache directory.
