Question

Hi I am using a code to get the referral URL as you can see below:

sRef = encode(Request.ServerVariables("HTTP_REFERER"))

This code is getting the following URL: http://www.rzammit.com/pages/linux-form.asp?adv=101&loc=349

From that url I want to grab the ADV and LOC (Request.querystring doesnt work)

Any help please on how I can do this? All this is happening in a script.

Answer 1

I can’t believe I have done this. ASP Classic IS my first web programming love so I had to 🙂

<%

URL="http://www.rzammit.com/pages/linux-form.asp?adv=101&loc=349&websync=ert4545445&put=4563"


Response.write ("adv = " + GetVarValue(URL, "adv"))
response.write("<br>")
Response.write ("loc = " + GetVarValue(URL, "loc"))
response.write("<br>")
Response.write ("adv = " + GetVarValue(URL, "websync"))
response.write("<br>")
Response.write ("gput = " + GetVarValue(URL, "gput"))
response.write("<br>")
Response.write ("put = " + GetVarValue(URL, "put"))
response.write("<br>")

%>

<br><br><br>



<%
function GetVarValue(Source, VarName)
    pos1 = instr(source, varname + "=")

'to check if the variable was not found
    if pos1=0 then
        GetVarValue="Not Found!!!"
        exit function
    end if

    pos1 = pos1 + len(varName) + 1

    pos2=instr(mid(source,pos1), "&")-1


'to check if it was the last variable
    if pos2=-1 then
        str1 = mid(source, pos1)
    else
        str1 = mid(source, pos1, pos2)
    end if
    GetVarValue=str1



End Function

%>

With this function in your page you can query any variable by passing the variable name and URL string to GetVarValue!
