Hi Chris, first let me do some shouting: "DONT USE USERAGENT STRING FOR DETECTING CAPABILITIES" ;))) This is highly forbidden and very stupid (this is the cause of all useragents calling themself "Mozilla" ;) Ok, now we are so far, how do we get the information? The useragent provides a header called "accept", which gives you the information what kind of documents it wants. Most developers use this field appropriate. (There are exceptions like M$ IE, which sends */* as acceptable mime-type, which is obviously wrong.) However, every WAP-Device I came accross so far uses text/vnd.wap.wml and stuff in its accept-header. All other devices are considerably broken. The correct implementation would be to negotiate with what you have (html, wml) and what the user-agent accepts. This would fail with IE, since it accepts all but cannot render WML, so you have to treat internally: "if it accepts explicitely wml, it gets wml, if not, it gets html" So you only have to scan for */vnd.wap* in the accept-header, like that: <dtml-if expr="_.string.find(_.string.lower(REQUEST['HTTP_ACCEPT']),'/vnd.wap') >0"> call your wml-producing object here (dont forget to set the appropriate mime-type and watch your encoding) <dtml-else> html-rendering here </dtml-if> Ok, the best solution would be not using dtml for this :) HTH Tino Wildenhain --On Mittwoch, 2.

Anyone doing browser sniffing with Zope to determine whether a user is coming in with and HDML or WML-enabled phone? I've got some leads on this, but I REALLY don't want to have to check for every USER_AGENT available. Is there a good way to check and see A) if it's a WML device B) If not, if it's an HDML device C) If it's not, is it an HTML device?

AND another wireless Zope conundrum. I'm serving some HDML pages from Zope. When I feed a Content-Type: text/x-hdml with the page, it doesn't show up on my Verizon Motorola 2260 phone. When I don't send the content-type, it does show up. The opposite is true on the Phone.com SDK phone browser--without a content-type, it chokes, but with a content type, it works. Any enlightenment?

Thankee! -- Chris Muldrow, muldrow@mac.com
