IE cannot display form response page from python server - WorldViz User Forum

Gladsomebeast · #1 11-21-2008, 04:58 PM

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'<html><head></head><body>POST OK.</body></html>'
		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.
