I have a classic asp page with 5 anchor tags. When clicking any one of the tag, i want to get the value of that href tag (or  the DocType value) and want to store that in a session.

<%
var strSearchUrl = getFilePath( "CustomSearchdsp.asp")
%>
            <TABLE id = customize margin-left = 49px; margin-right:49px;>
            <TR>
                  <TD><A HREF  = "<%=strSearchUrl%>?DocType=Ordinance"> Ordinance </A></TD>
            </TR>
            <TR>
                  <TD><A HREF   = "<%=strSearchUrl%>?DocType=Resolution"> Resolution </A></TD>
            </TR>
            <TR>
                  <TD><A HREF  = "<%=strSearchUrl%>?DocType=Agenda"> Agenda </A></TD>
            </TR>
            <TR>
                  <TD><A HREF  = "<%=strSearchUrl%>?DocType=Minutes"> Minutes </A></TD>
            </TR>
            <TR>
                  <TD><A HREF  =  "<%=strSearchUrl%>?DocType=Permits"> Permits   </A></TD>
            </TR>
            </TABLE>

use Request.QueryString on CustomSearchdsp.asp:

Session("docType") = Request.QueryString("docType")

if you want to get the FULL url (or the value of the href), you could do:

<% 
    prot = "http" 
    https = lcase(request.ServerVariables("HTTPS")) 
    if https <> "off" then prot = "https" 
    domainname = Request.ServerVariables("SERVER_NAME") 
    filename = Request.ServerVariables("SCRIPT_NAME") 
    querystring = Request.ServerVariables("QUERY_STRING") 
    Session("url") = prot & "://" & domainname & filename & "?" & querystring 
%>

Hi Monty, I tried both and they are not working. so, i am thinking of some script to get the clicked anchor href value and text value. Is there any way to do this.

This is my whole asp page and i am getting the value for Request.QueryString("DocType") as undefined

<%            
      expirePage();
      Response.Buffer=true;

      var uid = "DMUser";
      Session("user") = uid;
      var pwd = "password";
      var lib = "DOCSLIB_TEST";
      var alias = "";
      var IWAloginedUser = uid;
      var mustLogin = "N";
      var forceLogin = "N";
      Server.ScriptTimeout = 1200;

      var sysParms = new SystemParameters();
      var bis = sysParms.getBuiltInSymbols();


          bis.AllowAutoLogin  = 1;
      if(1 == bis.AllowAutoLogin)
      loginToLibrary( uid, pwd, lib, alias )

      setSearchLibraries();

      Session("Start") = "";

      if(Session("Start") == "")
      {
      strDocType = "" + Request.QueryString("DocType");

      Response.write(" this is a test " + strDocType);

       Response.write("sesson value 1" + Session("Start"));
           Session("Start") = 0;
      }
      else
      {
       Response.write("sesson value 2" + Session("Start"));
           Session("Start") = 0;
      }

      Session("noframes") = "YES";

      var strSearchUrl = getFilePath( "CustomSearchdsp.asp");

upon initial page load, yes, it'll be undefined. it will only populate once you click one of the links.

and just to clarify, this IS classic asp, and not asp.net, correct?

You are mixing ASP and Javascript/C# etc code - nothing to do with classic ASP

Things like this are the javascript/C# and other languages' way of writing code
      if(Session("Start") == "")
       {

    var strSearchUrl

@Gary: I saw that as well, and I'm assuming they are using server side javascript, they just don't have the tag on line 1 defining that.

@pothireddysunil: I tested the code out below and it works. I did have to un-comment some the javascript functions as I presume they're coming from an include file.

<%@language="javascript"%>

<%            
     // expirePage();
      Response.Buffer=true;

      var uid = "DMUser";
      Session("user") = uid;
      var pwd = "password";
      var lib = "DOCSLIB_TEST";
      var alias = "";
      var IWAloginedUser = uid;
      var mustLogin = "N";
      var forceLogin = "N";
      Server.ScriptTimeout = 1200;

      //var sysParms = new SystemParameters();
      //var bis = sysParms.getBuiltInSymbols();


      //    bis.AllowAutoLogin  = 1;
      //if(1 == bis.AllowAutoLogin)
      //loginToLibrary( uid, pwd, lib, alias )

      //setSearchLibraries();

      Session("Start") = "";

      if(Session("Start") == "")
      {
      strDocType = "" + Request.QueryString("DocType");

      Response.write(" this is a test " + strDocType);

       Response.write("<br/>sesson value 1" + Session("Start"));
           Session("Start") = 0;
      }
      else
      {
       Response.write("<br/>sesson value 2" + Session("Start"));
           Session("Start") = 0;
      }

      Session("noframes") = "YES";

      var strSearchUrl = ( "test.asp");
%>
<html>
<TABLE id = customize margin-left = 49px; margin-right:49px;>
      <TR>
            <TD><A HREF  = "<%=strSearchUrl%>?DocType=Ordinance"> Ordinance </A></TD>
