could you give an example of what flash is supposed to do?
it is possible, but probably not through html.
you can use in flash sendAndLoadVars to retrieve data from a php or html page, or you could make flash to read a txt or xml document, which contains the instructions what flash needs to do.
for more information on sendAndLoad Vars and xml-reading, take a look at the livedocs of flash:
http://livedocs.macromedia.com
or google for it.
