Interesting. I am using urllib2 to open some government pages, and they have some js checking for Flash on my computer.
Is there a way to show them that I have flash? Or possibly another solution? My code: user_agent = 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)' headers = {'User-Agent' : user_agent} req = urllib2.Request(_URL, None, headers) data = mechanize.urlopen(req) _soup = B_S(data) And what I get back from 'print _soup': <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head><title>Welcome to OurDocuments.gov</title> <!-- Prevent caching in netscape.
