Body
I have an ASP.Net site (happens to be MVC, but that's not relevant here) with a few pages I'd like cached really well. Specifically I'd like to achieve: <ol> <li>output cached on the server for 2 hours.</li> <li>if the file content on the server changes, that output cache should be flushed for that page</li> <li>cached in the browser for 10 minutes (i.e. don't even ask the server if it's that fresh)</li> <li>when the browser does make an actual subsequent request, I'd like it to use etags, so that the server can return a 304 if not modified.</li> </ol> (note - time values above are indicative examples only) <ul> <li>1) and 2) I can achieve by Response.Cache.SetCacheability(HttpCacheability.Server)</li> <li>I know 3) can be achieved by using max-age and cache-control:private</li> <li>I can emit etags with Response.Cache.SetETagFromFileDependencies();</li> </ul> but I can't seem to get all of these things to work together. Here's what I have: <pre><code> Response.Cache.SetCacheability(HttpCacheability.ServerAndPrivate); Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches); Response.Cache.SetETagFromFileDependencies(); Response.Cache.SetValidUntilExpires(true); Response.Cache.SetMaxAge(TimeSpan.FromSeconds(60 * 10)); </code></pre> Is the scenario I want possible? In particular: <ul> <li>can browsers do both 3) and 4) like that? When Firefox issues a new request after it expires in the local cache, it does indeed send the etag the server responded with before, but I get a 200 response. </li> <li>setting the variables like above, where would I set the duration of the output caching?</li> </ul> Thanks for any tips!

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
