<p>Do you think ASP.NET MVC is able to develop RESTful web services and which approach you would use for it?</p>
| <p>I have written a whole series of posts on developing a RESTful <a href="http://shouldersofgiants.co.uk/blog/" rel="noreferrer">Web Service using ASP.Net MVC</a>... well at least I'm 80% of the way through after 8 posts. Have a look at:</p>

<p>I am actually rendering an excel file in the browser. I use the Response.Writefile(filePath) to dod this. It is working perfectly fine in few of the machines. I am getting a pop up with "Open","Save" and "Cancel" option. </p>
<p>But incase of few machines after i do a save click on the popup a plain empty page rema... | <p>Are you setting any HTTP headers? If you are not, you are relying on the browser to interpret the data correctly.</p>
<p>To tell the browser you are sending excel content:</p>
<pre><code>Response.ContentType = "application/x-excel";
</code></pre>
<p>To tell the browser to treat the response as download:</p>
<pre... | <p>The problem with this approach is that date fields and number fields are all rendered as a string. The end user has to then explicitly modify the type for these fields if they want to sort them.</p>
<p>If you have the budget, I suggest using a component like:

<p>While writing a custom IHttpHandler I came across a behavior that I didn't expect concerning the HttpCachePolicy object.</p>
<p>My handler calculates and sets an entity-tag (using the SetETag method on the HttpCachePolicy associated with the current response object). If I set the cache-control to public using the S... | <p>I think you need to use HttpCacheability.ServerAndPrivate</p>
<p>That should give you cache-control: private in the headers and let you set an ETag.</p>
<p>The documentation on that needs to be a bit better.</p>
<p><strong>Edit:</strong> Markus found that you also have call cache.SetOmitVaryStar(true) otherwise t... | <p>If like me you're unhappy with the workaround mentioned here of using Cacheability.ServerAndPrivate, and you really want to use Private instead - perhaps because you are customising pages individually for users and it makes no sense to cache on the server - then at least in .NET 3.5 you can set ETag through Response... | 5,282 |
<p>So WPF doesn't support standard sorting or filtering behavior for views of CompositeCollections, so what would be a best practice for solving this problem. </p>

This should increase the revision number (at least it does in the AssemblyInfo.cs in C#).</p>
