[users@httpd] How to distinguish the first web page?
Hi.
Currently I am using mod_proxy_http module for http apache.
I would like to know how to get the very first page(text/html type)
among a series of returned pages.
For example, the following is a html of a site, www.foo.com. It has
two iframe in itself.
<html>
<iframe src="www.foo1.com".... >
............
<iframe src="www.foo2.com".... >
</html>
We get a html of www.foo.com, a html of www.foo1.com ,and then a html
of www.foo2.com in this order.
All of these pages have text/html type that I want to get.
My proxy wants to modify the very first web page only which is a html
of www.foo.com in the above example.
Is there any way to distinguish the main page and the other webpages
that is requested by the main page?
Thanks.

when user enters your web directly from URL line in browser or bookmarks, no
referer is set. If it enters your page via clicking on other page, referer
is set to the other page. Unless the user has browser plugin or proxy that
restricts referer from being sent (yes, that happens).
That is nearly everything you can get at thsi level. You can also set some
cookies and track them, but disabling cookies (for your site) is even easier
than disabling referer.

There is nothing like that in whole HTTP protocol, therefore nothing like
that in apache. HTTP is designed for transferring HTTP objects, and is does
not support sessions, pages, etc. IT's browser who requests for content and
man provide infromations like referer, cookies and user-agent to the server.
Think carefully what will you expect from your users and their browsers -
by implementing useless requirements you can even loose them.

Thanks. Krist van Besien.
I have used referer part of HTTP header. The problem is as follows.
Actually, I also need to keep track on where users go. In other words,
if I only use the refer part of URL header,
I cannot distinguish it from the case an user click one of the
hyperlinks. For this, I have used time check which may be weak.
I am looking for a better way than these referer & time check.
Is there a concept of level in apache? For me, the main page is top
level, but other iframe links of the main page is the lower level
than that. Or Isn't there a concept of ID for each page? I mean the
main page and other iframe links from the main page seems to belong to
the same page,that is the main page. If they share the globally-unique
id representing packets for the page, it would be helpful.
These two are imaginary way that I expect from apache. Is there
something like that in apache?
Or Any other suggestion?

You can look at the "referrer" field. This contains the URL of the
page the currently requested URL was found on.
