IE cannot display form response page from python server

I’m using a local python web server to receive data from a form displayed with HTMLViewer. Internet Exploder/HTMLViewer gives a “Cannot display page” error when the python web server attempts to write back a ‘Post OK’ message. When I just run the web server and submit the form with Firefox, it displays the message.

What does the web sever need to do for IE to display a form response page?

Here is the python code that handles the form POST request and writes back the response:

Code:

class MyHandler(CGIHTTPRequestHandler):



        def do_POST(self):

                global rootnode

                self.send_response(301)

                

                self.send_header('Content-type',        'text/html')

                self.end_headers()

                

                rawForm = self.rfile.read(int(self.headers['Content-Length']))

                parseDic = cgi.parse_qs(rawForm)

                

                stringy = r'POST OK.'

                self.wfile.write(stringy)

                

                e = viz.Event()

                e.resultsDic = parseDic

                viz.sendEvent(RECEVED_TEST_DATA_EVENT, e)

I have attached a zip with test files. Run QuestionAsker.py to reproduce issue.

I'm not sure what the problem is, but this sounds like an issue with Internet Explorer. Why are you sending a 301 response? Have you tried sending the OK response code, 200?

Sending the 200 response code works! However next time I try to process a form and send an response page it gives me the error page.

I guess it servers me right messing with protocols beyond my control.
