find parent frameset AND preserve page

I've looked all over for something that works, here is my challenge:

If clients search for employee webpages in our site, they can link directly to those pages.  I've put in some javascript to redirect them back to the frameset page:

if (window == top) top.location.href = "../../index.htm";

but I can't find a way to preserve the page they came from.  I've tried using URL strings (e.g., page.htm?id=thispage.htm,

but I'm not allowed to use server-side scripts to process redirects at the other end...meaning I need javascript that preserves the location of the page the clients were trying to access to begin with, or, some reliable way to read a URL string in javascript (I've found some that are either unreliable or too complicated for me)

Perhaps you can set a cookie to record the location and retrieve it later.

one other thing, how could I take (what method)

function getCookie(name) {
  var dc = document.cookie;
  var prefix = name + "=";
  var begin = dc.indexOf("; " + prefix);
  if (begin == -1) {
    begin = dc.indexOf(prefix);
    if (begin != 0) return null;
  } else
    begin += 2;
  var end = document.cookie.indexOf(";", begin);
  if (end == -1)
    end = dc.length;
  return unescape(dc.substring(begin + prefix.length, end));
}

and opent the name cookie in the right frame???

ADTCommented:
first set a cookie from the page the clients get in, write this in the <HEAD> section:

<SCRIPT language="javascript">
 if (parent.location != "http://...your index page"){
   setCookie(nameOfCookie,ThisPageName,expire);
   parent.location = "http://...your index page";
 }



function setCookie(name, value, expire)
// sets a value to a cookie
//  (Character string) name is the name of the cookie
//  (void)value is its value
//  (date)expire is the exiration date (may be null)
{
  document.cookie = name + "=" + escape(value)
   + ((expire == null) ? "" : ("; expires=" + expire.toGMTString()));
  return;
}
</SCRIPT>

Then in the index page, when opening, you can retrieve the cookie with a function like that:



function getCookie(Name)
// gets the value of a cookie
// (Character String)Name is the name of the cookie.
// The function checks if the cookie exists.
// It returns the value or null
{
  var search = Name + "=";
  if (document.cookie.length > 0)  // if there are any cookies
  {
    offset = document.cookie.indexOf(search);
    if (offset != -1)  // if cookie exists
    {
      offset += search.length;
      // set index of beginning of value
      end = document.cookie.indexOf(";", offset);
      // set index of end of cookie value
      if (end == -1)
         end = document.cookie.length;
      return unescape(document.cookie.substring(offset, end));
    }
  }
  return null;
}

and use the JavaScript docuement.write() to open the right page in the right frame if the getCookie(name) returns something :

 MyPage = getCookie(nameofCookie);
 if (MyPage!=""){
   document.write("<frame name'TheName' src='" + MyPage +"' frameborder='no'>");


to be tested of course...

better end with:

MyPage=getCookie(nameOfCookie);
if(MyPage!=null){
  document.write("<frame name='TheName' src='" + MyPage + "' frameborder='no'>");
}else{
  document.write("<frame name='TheName' src='TheNormalPage' etc..>;
}

Thanks for the help ADT, but I found a workaround without using cookies:
I used the writeline method to create the frameset
with a substring condition

     linkURL = "content.htm"
     if (parent.document.URL) {
          callingURL = parent.document.URL
          if (callingURL.indexOf('?') != -1) {
               linkURL = callingURL.substring(callingURL.indexOf('?')+1,callingURL.length)
          }
     }

     document.writeln('<frameset rows="70,395" cols="166,637" frameborder="NO" border="0" framespacing="0"> ')
     document.writeln('<frame src="title.htm" name="title" frameborder="NO" scrolling="NO" bordercolor="#000033">')
     document.writeln('<frame src="header1.html" name="title2" scrolling="NO" frameborder="NO">')
     document.writeln('<frame src="flashdetect.htm" name="nav" scrolling="NO">')
     document.writeln('<FRAME SRC="' + linkURL + '" NAME="content">')
     document.writeln('</frameset>')


Then pasted the relocation with a string parameter in each individual page:

if (top.location == self.location) {
               self.location.replace("../../index.htm?dept/faculty/albert_einstien.shtml")
          }

So simple...too bad I don't bill by the hour...too bad my employer loves frames.

once I figured out the writeln method, I could add whatever script i wanted to the frame source...can't take any credit though:
