I have set up apache + mod_wsgi and have done some playing with it to help
get some understanding of how client and server interact.
I am new to mod_wsgi and have not yet used it in anger, but the simple apps
I have written seem to be working ok.
However there is something I would like to understand regarding how the
browser decides when to render a page.
In the simple application below(tst1.wsgi) below I generate a simple html
page that contains an image, logging the REQUEST_URI
for each request.
If, in the browser, I type the url <myserver>/wsgipractice/tst1/index the
browser attempts to fully render the page and puts in a second request to
get the image. The log output containing the REQUEST_URIs looks like:
/wsgipractice/tst1/index
/wsgipractice/tst1/images/myimage.jpg
If, however, I type only the root url in the browser:
<myserver>/wsgipractice/tst1 the browser does not seem to attempt to render
the html page. No second request is put in to fetch the image. The log
output containing the REQUEST_URIs looks like:
/wsgipractice/tst1
It does not seem to matter what comes after tst1 in the url (I can type in
tst1/bob, or even simply terminate with separator: tst1/).
Does anyone know what it is that triggers the browser to fully (or not)
render a page ?
tst1.wsgi

import os
def get_page(environ, mime_type):
html_str = \
('<html><body>'
'<center><p style="font-weight:bold;">LARRY HOME</p></center>'
'<div style="background-image: url(images/myimage.jpg)">'
'<a href="http://google.com";>'
'<div>Home</div></a>'
'</div>'
'<br><p>Body</p><br></body></html>')
return html_str, mime_type
def application(environ, start_response):
status = '200 OK'
output = u''
log_file = open(('/logs/tstpagegen.log'), 'a')
log_file.write(environ['REQUEST_URI'] + '\n')
log_file.close()
output, mime_type = get_page(environ, 'text/html')
response_headers = [('Content-type', mime_type),
('Content-Length', str(len(output)))]
start_response(status, response_headers)
return [output]
