I'm quite new to Magento, and i'm looking into the following, wondering if it's possible.
at some point magento will need to do some echo'ing to the client, ie. stream it's html data to the client. At what point does this happen? Along its execution, or is the output gathered and sent at the end?
I'm looking into a way of inspecting/modifying the html of a page in a generic way, so not from inside a template or something.
Is this possible?
