How do you specify your Content Type in ASP.NET WebForms?

Question

I'm specifying my doctype as xhtml strict, but it's being sent over the wire as a content type of text/html. I'd like to specify that the content type is application/xhtml+xm, but I can't figure out where, or if, I can configure this from within my application

BTW, after doing this, just about every browser took a dump on me. So I left it the way it was being sent. Web standards, you gotta hate 'em. — , Oct 08 '08 at 14:17

You can specify it in the @ page attributes section, like this:

<%@ Page ContentType="application/xhtml+xm" %>

...more on MSDN.

Can't do it from the master? Urgh. – Oct 06 '08 at 16:11
Sadly, it does not appear so. – Mitchel Sellers Oct 06 '08 at 16:24
I guess you could set it via Response but that might get a bet sketchy in terms of functionality – Mitchel Sellers Oct 06 '08 at 16:25
Yeah, Response would be the only from from the master page. – Tom Oct 06 '08 at 17:40

Classic example of [why link-only answers are a bad idea](http://meta.stackexchange.com/questions/8231/are-answers-that-just-contain-links-elsewhere-really-good-answers). The answer didn't actually answer the question unless you followed the link. The link died, making the answer completely useless. I've fixed it -- by fixing the link (for now), but more importantly by actually putting the answer **in** the answer. – T.J. Crowder Dec 27 '12 at 12:56

In your code behind file, during the Page_Load event, try addind the following code:

Response.Clear()
Response.ContentType = "application/xhtml+xm"

That's the property you want, but you'll probably want to set it sooner than load (maybe Pre_Init) – John Sheehan Oct 06 '08 at 16:08

Your code is not related to the question, but it helped me- see http://geekswithblogs.net/mnf/archive/2011/09/23/change-doctype-dynamically.aspx — Michael Freidgeim, Sep 24 '11 at 02:39
