Re: need some help in serving static files inside a wsgi apps
I guess, Apache does some kind of memory caching for files, which are often requested and small enough to fit into the system memory. Are you sure about this? I could not find anything in the documentation (other than mod_cache and friends, which is an unrelated functionality). Also, I don't see the need for Apache to cache frequently requested files itself. Instead, the operating system will cache frequently requested directories and files in memory, and it will do the same for a Python web server.

Instead, the operating system will cache frequently requested directories and files in memory, and it will do the same for a Python web server. Of course, a modern OS kernel will perform caching anyway, but this is most likely slower than in-process caching, since it will still require context switches from userspace into kernel space. Considering this, it seems reasonable to me, that apache does memory caching, but I'm by far not sure, I wouldn't put a bet on this ;) - -- Freedom is always the freedom of dissenters.

Interestingly enough, this *doesn't* do memory caching for files. Instead, it either keeps the file handle open, so you can seek to the beginning of the file on the next request (avoiding the directory lookup), or you can mmap the file. However, even if you mmap the file, it is still the operating system's choice whether or not to cache the file contents in memory.

need some help in serving static files inside a wsgi apps
Hi, Until now, I was running my own static site with Python, but I'm in need of dynamism. After reading some cgi tutorials, I saw Joe Gregorio's old article Why so many Python web frameworks? about wsgi apps [http:// bitworking.org/news/Why_so_many_Python_web_frameworks] and have a question about it. The code he gave works like a charm (I had to make a little change because SQLAlchemy has changed since), but how the hell can I serve static files (css, js, images, etc.) within an wsgi app, ie inside a '/static' directory ?! Sorry if my question is a stupid one, but I cannot find an easy way to do this. Each tutorial I'm reading out there does not talk about them at all. All of my python books didn't mention wsgi either. I know I could use web.py, web2py, Cherrypy, Django, Pylons, etc. but I'm trying to understand basics of web dev. from their roots. thanks in advance for any advice , Kib. -- http://mail.python.org/mailman/listinfo/python-list

Hi Diez,
and thanks for yout help. In fact I already found it but never managed
to get it work because the static doc says :
from wsgiref.simple_server import make_server
import static
make_server('localhost', , static.Cling('/var/www')).serve_forever()
and inside J.Gregorio's tutorial it is:
from wsgiref.simple_server import WSGIServer, WSGIRequestHandler
httpd = WSGIServer(('localhost', 8080), WSGIRequestHandler)
httpd.set_app(urls.urls)
It does not use 'make_server()' so how can I adapt it ?
I finally managed to work with static files with a little hack, but it's
ugly because I'm reading each static file per request.
Kib.

static.Cling is a wsgi-app. The other code just makes a specific
wsgi-implementation based server out of it.
I finally managed to work with static files with a little hack, but it's

How else should that work? Apache does that the same way.
