问题
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
回答1:
You can specify it in the @ page attributes section, like this:
<%@ Page ContentType="application/xhtml+xm" %>
...more on MSDN.
回答2:
In your code behind file, during the Page_Load event, try addind the following code:
Response.Clear()
Response.ContentType = "application/xhtml+xm"
