pages: HTTP cache headers handling:
when checkCache is used, HTTP headers handling cache are now used:
- ETag is first checked, using a hash of the rendered content
- Last-Modified is used as a fallback is client is not handling ETag
When suitable, a HTTP 304 code (Not Modified) wihtout body is returned instead of the whole page.
