Wildcard character available in asp classic?

I'm got a site with classic asp using vbscript. How can I check if a user is coming from a certain directory on my site? I've got this code

<%Response.Write(Request.ServerVariables("http_referer"))%>

which writes: http://ift.tt/1VDXVHq. I'd like to write an if/else statement that first checks if the referring uri is in the directory http://ift.tt/110aiFa.

So my code should be something like the below. But I'm not sure about syntax. Is there such a thing as a wildcard character is asp?

<% Request.ServerVariables("http_referer") == "http://ift.tt/1VDXVHs"

Eventually I'd like to use that to write an if /else statement

<% if Request.ServerVariables("http_referer") != "http://ift.tt/1VDXVHs" then 
null; elseif (screen.width <= 699) {
    document.location = "/mobile/mobile_home.asp";
  } %>
