Xhtml Support detection

[sidduexpert]

Hi All

Is there any way(I mean any Header information) where we can know ,whether the Users mobile supports Xhtml .

For example, When a user access a url, i need to know, whether his mobile phone supports xhtml, if yes, i want to redirect him to an Xhtml site ,else i will redirect him to an exisisting wml site.
(Currently , i am using a global constant which contains all the mobile phone models as comma seperated and i am checking this with the http_user-agent. )

Are there any specific headers where we can know, if the user mobile supports xhtml or not.

Please help.

Check browser's Accept content for:

application/vnd.wap.html+xml

application/vnd.wap.xhtml+xml

application/xhtml+xml
or
application/xhtml+xml; profile="http://www.wapforum.org/xhtml"

Hi there,

I had the same question but I'm a complete newbie... so how exactly do you test to see what a browser can accept?

thanks in advance

Hi Rich.

You can know the entire browser information by looping thru, ServerVariables collection.To exactly know the Phone Model
U need to request for a servervariable called Http_User_agent

This Piece of code will exactly return the phone model
=======================================
lstrUA=Request.ServerVariables("HTTP_USER_AGENT")
lintSlashPos = InStr(1, lstrUA, "/")
lstrPhoneModel=Mid(lstrUA, 1, lintSlashPos - 1)
======================================

This Piece of code will return the mobile number which requested the page
=======================================
lstrMSISDNThru = Request.ServerVariables("http_x_up_calling_line_id")
=======================================

But when i tested with Nokia3650 Mobile, I am not able to get the required browser information(i.e the screen resolution of the mobile,Xhtml/Wml Support etc).

So i followed a little bit lengthy process to get the above information which was required for my current project.

There is a concept called as UAPROF profiles.Its an xml file which contain most of the details of a particular model.
U can check the UAPROF here(http://w3development.de/rdf/uaprof_repository/ , and can download them under REAL WORLD PROFILES section)
So when a user lands on a Page, i get the phone model from HTTP_USER_AGENT header and call the related xml file and get the screen size and wap browser version of that particular mobile.
