asp 301 seo redirect upper / lower case

I posting on forums and blog how seo = 301 …

So last few day i’ve spotted some dup content issues which i’ve been fixing with a new 301 script that check the case of a query making sure that only the 1 case is ever indexed..

What goes wrong:

page.asp?case=HELLO

vs

page.asp?case=hello

Â

Both the above would return the same page..

Â

thesku=Request.ServerVariables(“QUERY_STRING”)
nothesku=Left(Right(thesku, Len(thesku)-5),1)

thesku=Left(Right(thesku, Len(thesku)-4),1000)

nothesku=(ASC(nothesku))

if (nothesku>96)then
thesku=UCase(thesku)

‘you can change the below to whatever you page name is..Â

thesku=”page.asp?case=”&thesku

Response.Write(“change to uppercase”)

end if

Response.Write(thesku)

Â

The above checks the Ascii value for the first char and if lower will write out the page location in upper case.. By adding a simple 301 redirect to this its will pass the value to the correct no dup page..

Â

Problems and bugs with the above..

It only check the first letter.. now for me this is fine but you can of course loop and check each letter..
