Very often we are confronted with a situation where we need to have different versions of the same site based on the country of origin of the user. There are many reasons for this.
The content could differ in terms of registration forms or we might even have different language fonts for the regions. Another reason could be that you want to make a census as to how many people are coming from say INDIA or say from The WEST INDIES. What ever be the reason this article helps you build a foundation on which to improvise.
It also comes with a Download version(zipped) of the coding. This article is meant to help create an asp program which will have the ability to redirect users based on their georaphical location. I have used a downloaded list of IPv4 ranges for india and written the code.
Here is a step-by-step approach to the problem...
Step 1 : Get the list of IPv4 ranges for the region of your choice
(Look into www.apin.org for a beginning) and extract the ip's into a text file say call it ip.txt.
Step 2 : Get the IP address of the user and split it into an array with "." as the delimiter
Step 3 : Load the IP addresses from up.txt into a 2 dimensional array
Step 4 : Now for each IP range split the starting ip and ending ip into two arrays
Step 5 : Compare the corresponding numbers of the user ip array with those of the
fromip and toip arrays
Step 6 : Repeat Step 4 thru Step 5 in a while loop till u reach the end of the array.
Now Go thru the snippet of code below and readthru the comments to understand it line by line. dim ipfromto(45,45)
yourip=split(request.ServerVariables("remote_addr"),".")
realpath=server.MapPath("./iponly.txt")
set myobj = server.CreateObject("scripting.filesystemobject")
set myfile = myobj.OpenTextFile(realpath)
i=1
while not myfile.atendofstream
line=myfile.readline
temp=split(line,"-")
ipfromto(i,1)=temp(0)
ipfromto(i,2)=temp(1)
i=i+1
wend
myfile.close
flag=false
j=1
While j< 46
'split the from-ip and to-ip based on "."
'fromip has the from ip address in four parts
'toip has the to ip address in four parts
fromip=split(ipfromto(j,1),".")
toip=split(ipfromto(j,2),".")
if yourip(0) > = fromip(0) and yourip(0) < = toip(0) then
if yourip(1) > = fromip(1) and yourip(1) < = toip(1) then
if yourip(2) > = fromip(2) and yourip(2) < = toip(2) then
if yourip(3) > = fromip(3) and yourip(3) < = toip(3) then
flag=true
end if
end if
end if
end if
if flag=true then
'Put your response.redirect() here
flag=false
else
'Put your response.redirect() here
end if
j=j+1
wend |
