displaying an image based on the URL of the website
Posted on 2004-10-18
i have a website that has 3 different urls and they are all going to the same IP
i have a single image that says the name of the site on the top of all my pages
i want to create 3 differetn images each showing a different domain name and i would like to get it so depending on the URL the person entered the site, it shows the right image so the domain and the graphic is consistent with the site name.
wondering how id write the script to check for the requested URL server variable and then have the href that displays the image swap to the appropriate version of the image based on the URL

I have done this many times - you can become very dynamic with this type of coding.
The following example looks at the URL that was entered into the browser window and simply asks an If Contains Question to determin what image to use:
' This line get the URL that was requested
TURL = CStr(Request.ServerVariabl
' This code looks for the string "website1" in the URL
' ( such as http://www.website1.com/ ) and if it exeists,
' assisgnes image #1 to the SHOW_IMG Variable:
If InStr(TURL, "website1") > 0 Then
SHOW_IMG = "image1.gif"
End If
' This line looks for the string "website2" in the URL
' ( such as http://www.website2.com/ ) and if it exeists,
' assisgnes image #2 to the SHOW_IMG Variable:
If InStr(TURL, "website2") > 0 Then
SHOW_IMG = "image2.gif"
End If
Then, where your Graphic should be placed - use:
<img border="0" src="images/<% =SHOW_IMG %>">
Have fun, Good luck!

hm not sure what im going wrong here but this is exactly how ive tried it.
<% TURL = CStr(Request.ServerVariabl
<%If InStr(TURL, "http://www.domain1.com/") > 0 Then
SHOW_IMG = "1.jpg"
End If%>
<%If InStr(TURL, "http://www.domain2.com/") > 0 Then
SHOW_IMG = "2.jpg"
End If%>
<img src="plastic_images/<% =SHOW_IMG %>" width="754" height="424" border="0" usemap="#Map">
if u see anything i did wrong let me know. im still messin with it. thanks for the start!

This code is working perfectly, there is no error. If you tell what is the error u're getting it will give us more clear picture!
Cheers!!

OK - Try this:
In this line:
If InStr(TURL, "http://www.domain1.com/") > 0 Then
Try using less of the string to search for. For example, you could just look for "1" like this:
If InStr(TURL, "1") > 0 Then
The issue is probably that the ENTIRE string must match the InStr search so it may not be finding the last "/". InStr is command for In String so the if statement asks If "1" is in the string that is called TURL then do this.
Make sense? Can you give me the two domains that are pointed to your site?

But what if someone enters
http://69.20.52.76/
http://69.20.52.76/
Can you change this line:
<% TURL = CStr(Request.ServerVariabl
to:
<%
TURL = CStr(Request.ServerVariabl
Response.Write(TURL)
%>
This will show us what the value of TURL is and may help us solve the problem.
