Need help with server side scripting.

HI! I have an iframe in which the iframe gets its height value from a
session variable. The value gets passed to the session ok because I am able
to display it but the main Iframe does not get updated with the new value
that has being passed to it. how can I accomplish this?

After the main page loads its height is at 620px. if a click on a link which
passes the value 1000, the variable does hold the new value 1000 BUT the
iframe height is still 620 if I do a view source. how can I update the
iframe value so it reloads using the new value?

I don't want to reload the whole page by doing a meta refresh either because
I have flash scene which I want to keep at it scene.

I was told that the page must be requested from the server in order to use
the session value or to see a change in
the value, since ASP is server-side technology.

Can someone give me an example on how I may use the way with the above
problem?

Example. The first Main page.----NOTE: ignore the ifp value its to set a
default page------------

<% Session("ifh") = Request.QueryString("ifh") %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
<html>
<head>
<title>Untitled Document</title>
</head>
<body>

<%
dim ifp
ifp = Request.QueryString("ifp")
if ifp <> "" then
%>

<iframe src=<%= ifp %> id="Iframemain" name="Iframemain"
height="<%=Session("ifh")%>"
width="760px"></iframe>

<% else %>

<iframe src="Main_iframe_Pages/main.htm" id="Iframemain" name="Iframemain"
height="620" width="760" ></iframe>
<% end if %>

</body>
</html>
-------------End of main page.------------------------

From a menu link I pass the value like such.

Main_iframe_Pages/about_us.asp?ifh="1000"

If you do not wish to reload the page, the iFrame resizing must be
done client-side, not using ASP. This means writing JavaScript to
resize the iFrame and redraw the page (and as a consequence the page
layout will change).
The link to the new page becomes something like
<a href="pagename.htm" target="Iframemain"
onclick="reSizeIframe(1000)">next page to display in Iframe</a>

The function reSizeIframe changes the Iframe height property, and
redraws the page. I have no idea whether this is actually possible or
not, but using ASP will require the entire page to be reloaded with a
different src and height for the iFrame - which would restart the
flash presentation.

Your Iframe will never change size on the receiving page if you don't also pass ifp as a parameter, due to your
If statement value for ifp always being = ""
You are only passing ifh with Main_iframe_Pages/about_us.asp?ifh=1000 and not ifp
But you are checking for ifp with: if ifp <> "" then
- so what do you expect and where do you expect ifp to get a value from?

For your use neither should be a session variable, just a page variable as

Main_iframe_Pages/about_us.asp?ifp='someotherIframe.htm'&ifh='1000'

On the receiving end you just need
<%
dim ifp, ifh
ifp = Request.QueryString("ifp")
ifh = Request.QueryString("ifp")
if ifp <> "" then
%>
<iframe src=<%=ifp%> id="Iframemain" name="Iframemain" height="<%=ifh%>" width="760px"></iframe>
<% else %>
<iframe src="Main_iframe_Pages/main.htm" id="Iframemain" name="Iframemain"
height="620" width="760" ></iframe>
<% end if %>

IMHO
Passing an Iframe page URL as a parameter variable is risky because it is too visible
Could let me insert a URL of my own w/ some dangerous code in my iframe page
