This page uses frames, but your browser doesn't support them. Sorry!

When I use Data Socket Read to view a web page HTML, I receive an error stating "<p>This page uses frames, but your browser doesn't support them. Sorry!</p>
".
How can I read the HTML of all or a specific frame of a web page?

Are there sites out there that still use frames? Egads!
Essentially you have to know the actual page that's contained within a frame. A frame page is just a placeholder for other pages. If you actually get the source for a frame page you would see that it lists other pages as being contained within a frame. In essence, it's like having multiple browser windows inside of a single page.

I'm actually try to read a web page that is resident within a piece of equipment and that page still uses frames. I've tried to use a vi that I found posted , get_HTML.vi. I returns the html from the top frame but I don't know how to format the input to request the lower level frames.

There is no special way to format the input. You just need to request the specific page that's being displayed in the frame. If you've gotten the page you can look at the source code (i.e., the HTML code) and see the name of the page. Then you just need to request that page instead of the frame page.

You are probably getting some html that looks something like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"
"http://www.w3.org/TR/html4/frameset.dtd">
<HTML>
<HEAD>
<TITLE>A simple frameset document</TITLE>
</HEAD>
<FRAMESET cols="20%, 80%">
<FRAMESET rows="100, 200">
<FRAME src="contents_of_frame1.html">
<FRAME src="contents_of_frame2.gif">
</FRAMESET>
<FRAME src="contents_of_frame3.html">
<NOFRAMES>
<p>This page uses frames, but your browser doesn't support them. Sorry!</p>
</NOFRAMES>
</FRAMESET>
</HTML>
(although your frameset and frame tags will amost certainly be different)
What you will need to do is parse out the <FRAME> tag src elements and fetch those pages instead.
e.g. if the home page is http://mysite.com/index.html and the frame tag is <FRAME src="frame1.html">, you will need to fetch http://mysite.com/frame1.html

Problem solved! Once I realized the actual page name and that it was a *.cgi page, my get_html.vi worked really well. Thanks to everyone for the help.

I had the same question and solved it through the method. You can apt-get install php libapache2-mod-php and then restart apache2 and nagios.
