the most probable cause for this error is that the page does not actually exist.. have you tried visiting http://127.0.0.1/sample/sample.asp or http://localhost/sample/sample.asp directly from your browser? The IFrame module does nothing fancy, it just puts an iframe in a page, with as source attribute the page you want to display.

Can you try this in just a plain html file:

<iframe src="http://127.0.0.1/sample/sample.asp"></iframe>

if this is working, you probably entered the wrong parameters in the iframe module.

Cheers,

Erik

I had learnt this through a thread in the forums, that Iframe module tries to validate the URLs entered, by using a 'regular expression'. This RegEx does not accept the string  "http://localhost..." (i don't know why was it designed like that). The work around mentioned in the thread was...

1. open EditIframe.ascx (in the folder C:/dotnetnuke/DesktopModules/) in notepad.

2. near the top of the file locate the section-

<td width="400"><asp:textbox id="txtSrc" cssclass="NormalTextBox" columns="50" runat="server" />
            <asp:regularexpressionvalidator id="valURL" runat="server" cssclass="NormalRed" controltovalidate="txtSrc" errormessage="You Must Enter a Valid URL"
                display="Dynamic" resourcekey="valURL.ErrorMessage" validationexpression="^((http|https)\://)?[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&amp;%\$#\=~])*[^\.\,\)\(\s]$"></asp:regularexpressionvalidator></td>

3. delete the section in bold i.e. <asp:regularexpressionvalidator .. .. ... ..</asp:regularexpressionvalidator>

4. Save it.

URLs wont be validated in iframe module now.

However i dont know how healthy is this approach ...
