XHTML and FirefoxI'm sure some of you more seasoned developers who use Firefox all the time already know this, but I discovered something about using XHTML document types when it comes to Firefox. I discovered that Firefox is a lot more strict about mime types when you tell it the document is XHTML.
First off, how do you tell the browser the mime type and document type? Starting in Notes 5, you had the ability to change the content type of forms away from the default of "Notes" (where Domino would put in its own <HTML> tags). Doing this meant you had to code the entire web page. Back in the earlier days, there was an assumed document type for each web page. If you did specify the document type, it would look something like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
Keep in mind that this only applies if you're specifying the XHTML document type and are using Firefox. But when you're keeping up to date with standards and making your Domino web site available to multiple browsers, you need to keep this in mind.
