HTML Content within <iframe>

[learnerguy]

Hi:

Does Search Engine index HTML content that uses

<iframe> </iframe>

Say in an HTMl file I have normal HTMl content, and also I use an

<iframe> </iframe> that calls a script which returns HTML content.

Will search engine index the resulting HTML page as well as the <iframe>'s HTML content, or it will just index the <iframe> as an <iframe> without the resulting content ?

Thanks in advance :confused:
