Thanks for the quick reply. I threw something together and just wanted
to know if this is the right approach:
output = ""
def application(environ, start_response):
def echo(input):
global output
output += str(input)+"\n"
name = "Shady"
br = "<br/>"
echo("""<html>
<head>
<title>Test</title>
</head>
<body>
<h2><center>Hello World</center></h2>""")
echo('Hello %s. Welcome to my world!' % name)
echo(br*2)
echo('This can be a fine alternative...')
echo('</body></html>')
start_response('200 OK', [('Content-Type', 'text/html')])
return [ output ]
Would using such a function to replace the print command be a feasible
workaround? That way it'd be much easier to port my code.
I've looked at other frameworks such as Django, but it looks too
intimidating. Right now I just want to refine my Python skills, but if
Flask is simple and easy to use, I'll look into it.
Just a few more questions:
1. How do I access multiple *.wsgi files in a directory using
WSGIScriptAlias? When I type in localhost/wsgi/ (the path I assigned
it to) I want to access another file other than the primary one. For
example 'localhost/wsgi/app2.wsgi'.
2. Mod_wsgi is compatible with MySQL right? If so, can it handle user
sessions? (log in with username and password)
3. Is there anyway to manually asses how much of an improvement my
wsgi script is over CGI?
Once again thanks for the help. I'll look into the 'Learn WSGI' web
page later tonight.
