Detecting the browser type - on the server side
The article is some good code for detecting the browser type - on the server side. Itdelivers the right page while processing based on the browser type intsead of doing aredirect while the page is loading. It sends IE5 one way, IE4 another way, (or IE4& IE5 the same way), and everybody else another way. This is just one way ofcoding to really be detailed to which browser the user is using. Here is the Code <%@ Language=VBScript %>
<%
Dim sAgent,b_IE,b_Vers,b_Mac,b_Nav,b_Other
Dim ie4win,b_win,ie4,ie3,ie4mac,ns4
b_IE=false
b_Nav=false
b_Other = false
b_Vers = 0
sAgent = Request.ServerVariables("HTTP_USER_AGENT")
if (inStr(sAgent,"MSIE")>0) then
b_IE=true
b_Vers = Mid(sAgent,inStr(sAgent,"MSIE")+5,1)
elseif (inStr(sAgent,"MSPIE")>0) then
b_Vers = Mid(sAgent,inStr(sAgent,"MSPIE")+9,1)
else
b_Vers = Mid(sAgent,9,1)
end if
if (not (b_IE)) then
b_Nav=inStr(sAgent,"Mozilla")>0 or inStr(sAgent,"compatible")>0
end if
b_Win = (instr(sAgent,"Win")) > 0 'Windows
b_Mac = (instr(sAgent,"Mac")) > 0 'Mac
b_Other = not (b_Win or b_Mac) 'Other
ie4 = b_IE and b_Vers>=4 ' IE4
ie5 = b_IE and b_Vers>=5 ' IE5
ie3 = b_IE and b_Vers<4 ' Everything <IE4 we consider IE3
ie4Mac = b_Mac and ie4 ' IE4 Mac
ns4 = b_Vers>=4 and b_Nav ' NS4
ie4Win = b_Win and ie4 and not b_mac ' IE4 Windows
%>
<%
if ie5 then
' Send this File to IE5
response.write("simple1.htm")
elseif (ie4) then
' Send this File to IE4
response.write("simple2.htm")
else
' Send this File to other browsers
response.write("simple3.htm")
end if
