Detecting mobile phone browsing

Question

Trying to find a solution to detect if a user is browsing a
specific web site from a mobile device, and then redirect them to a
simplified version of the site?
Any ideas?

Answer 1

You could do as darrel has suggested and but if you want
automatic redirection the you want to put a script in place that
detects what useragent a browser is using. Below are some. the
WURFL database will give you huge list of useragents.
IE 6 .0 on Windows XP SP2 with .NET Framework 1.1 installed:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR
1.1.4322)
IE7 beta running on Windows Vista — Mozilla/4.0
(compatible; MSIE 7.0b; Windows NT 6.0)
Firefox 1.5b1 on Windows XP — Mozilla/5.0 (Windows; U;
Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Opera 8.51 on Windows XP — Opera/8.51 (Windows NT 5.1;
U; en)
Pocket PC IE on Windows Mobile 2003 — Mozilla/4.0
(compatible; MSIE 4.01; Windows CE; PPC; 240x320
Nokia 6230 Mobile Phone:
Nokia6230/2.0+(04.43)+Profile/MIDP-2.0+Configuration/CLDC-1.1+UP.Link/6.3.0.0.0
You will need to use ASP which is server-side detection
rather than javascript with alot of mobile phones have trouble
with.
You could try this code below, though you wil need a large
list of user agents:
<%
userAgent = Request.ServerVariables("HTTP_USER_AGENT")
isMobile = false
if((InStr(userAgent, "AvantGo") > 0) OR (InStr(userAgent,
"Windows CE") > 0) OR (InStr(userAgent, "NetFront") > 0) OR
(InStr(userAgent, "BlackBerry") > 0) ) then
isMobile = true
end if
if isMobile then
response.redirect("
http://www.namesandnumbers.com/mobile")
end if
%>
Hope this helps
