python - Scraping Flash: accessing background files, perhaps in Mechanize? -

I'm scraping a website into Flash, typing in Python. I can see in the firebug that the page loads its flash file and then some background data in the .asmx file.

Background data is what I'm interested in - how can I get the .asmx file? I already know what it is called.

I can not go directly to the .asmx file, but can I hold it via the macenic?

--- Update ----

I have a scrap page

.asmx file - I can see it in firebug.
