If Statements and SEO

Hi There,

I'm working on improving Search Engine Optimisation code for a website I'm working on which is built in asp.net c (sharp).

I usually work in classic asp, so I'm finding where to start with getting asp.net equivalent code from what I use with classic asp is very difficult, to say the least.

Basically, the code I'm trying to find code in asp.net for - grabs the filename from the address bar and uses if statements to replace the page title, keywords and descriptions with different content depending on which page it is on. I have the asp code below:

<%
function curPageName()
 dim pagename

 pagename = Request.ServerVariables("SCRIPT_NAME") 

  if inStr(pagename, "/") > 0 then 
    pagename = Right(pagename, Len(pagename) - instrRev(pagename, "/")) 
  end if 

 curPageName = pagename
end function 

currentPage = curPageName()
%>
<%

if vPage = "Home" then 
	vDx = "Specialists in Income and Family Protection insurance. Our Lifestyle Protection Plan is a premiere product specifically tailored to Protect You and Those Dear To You. For a more in-depth view visit insurance1.co.nz"
	vWords = "Insurance 1, Insurance One, New Zealand, insurance, Tony Wilson, income protection, disability protection, life cover, living assurance, family protection, asset protection"
	vTitle = "Insurance 1 - Protecting You And Those Dear To You..."
end if
&>

Has anyone done something like this before in .net and may be able to shed a little light or does anyone know of any tutorials or code snippets that may help with this?

Any ideas would be greatly appreciated!

Cheers,
Chris
