Sorry for delayed response.
Static cache is a pre generated static cache, so it has no way of knowing about used view parameters. If you want to have static cache for those, then you should look into using a reverse proxy instead (ie: Varnish or Squid).
I made a extension http://projects.ez.no/lastaticcache
1. it can be used for the page with view_parameter
2. to avoid generet the bad page with error.
3. don't add "/content/view/x" in table ezpending_action 4. filter don't add custom page in ezpending_action
