WML headers

Hi I build a wap site, and it is supposed to be WML 1.1 compatible.
So the first question is how can I validate my code that it is WML 1.1 and not another version of WML.
The Second question is .What are those headers that appear in my code when I view source in an emulator.
And why should I user the
<?xml version="1.0" encoding="iso-8859-7"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
???
I will show you a sample.

Code:

HTTP/1.1 200 OK
Server: Microsoft-IIS/5.0
Date: Tue, 18 Apr 2006 13:44:34 GMT
Cache-Control: no-cache
X-Powered-By: ASP.NET
Pragma: no-cache
Cache-Control: no-cache,must-revalidate
Connection: Keep-Alive
Content-Length: 1327
Content-Type: text/vnd.wap.wml
Expires: Tue, 18 Apr 2006 13:44:34 GMT
Cache-control: private
--[ HEADER END ]------

xml Code:

Original - xml Code

<?xml version="1.0" encoding="iso-8859-7"?> 
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"  "http://www.wapforum.org/DTD/wml_1.1.xml">

Hi,

So the first question is how can I validate my code that it is WML 1.1 and not another version of WML.

You can use online validators: here is one, and here is another. Actually w3schools has some pretty good information on this, including http://www.w3schools.com/wap/wml_reference.asp.

Code:

HTTP/1.1 200 OK // It was a request and it was OK
Server: Microsoft-IIS/5.0 // your hosts server
Date: Tue, 18 Apr 2006 13:44:34 GMT // date
Cache-Control: no-cache // the page won't cache
X-Powered-By: ASP.NET // software you are using 
Pragma: no-cache // the page won't cache
Cache-Control: no-cache,must-revalidate // the page won't cache
Connection: Keep-Alive // server setting
Content-Length: 1327 // size of the fiel
Content-Type: text/vnd.wap.wml // sending as wap content type
Expires: Tue, 18 Apr 2006 13:44:34 GMT // expires
Cache-control: private // again caching thing, more suitable for IE, but OK

There was a question posted in the PHP forums the other day and someone gave quite a good explaination about what everything meant, can't find it off-hand.

As to your last question: because you just should

But in all seriousness, it enables the browser / device to understand what it is downloading and can interprete it accordingly.

Check the resources link in my signature, there are some pretty useful links in it.

Hope that helps.

thanx

ok thanks

.
One last thing .. when i validate my WML code i validate only the content between the <wml>...</wml> tags
not the header info and the <XML> that tells the browser that the content is about wml correct??

Your page should be

PHP Code:


		
			
<?xml .....

</wml>

The xml declaration is an important part of the process.
