problem with web.changequery

[Anand]

I am using a lighttp+fastcgi to run my web.py application with the
following rewrite rule.

url.rewrite-once =(
"^/(.*)$" => "/run.py/$1",
)

When i use web.changequery, it includes /run.py in the changed query.

For example when i am at url /hello and call web.changequery
(m="edit"), it gives
/run.py/hello?m=edit
instead of
/hello?m=edit

I think it is because web.changequery addes web.ctx.homepath to the
web.ctx.path before changing the query.
any workarounds?

Yes, I think you can use lighttpd to set the environment variable
REAL_SCRIPT_NAME to include run.py and then web.py should strip it out

How to set environment variables from lighttpd?

I tried setting REAL_SCRIPT_NAME by executing
os.environ['REAL_SCRIPT_NAME'] = "/run.py"

But it doesnt work.

web.py doesnt strip anything in setting homepath. This is the code,
which sets ctx.homepath and ctx.path

ctx.homepath = os.environ.get('REAL_SCRIPT_NAME', env.get
('SCRIPT_NAME', ''))
ctx.path = env.get('PATH_INFO')
# http://trac.lighttpd.net/trac/ticket/406 requires:
if env.get('SERVER_SOFTWARE', '').startswith('lighttpd/'):
ctx.path = lstrips(env.get('REQUEST_URI').split('?')[0],
os.environ.get('REAL_SCRIPT_NAME', env.get
('SCRIPT_NAME', '')))

However setting REAL_SCRIPT_NAME to "" solved the problem.

btw, http://trac.lighttpd.net/trac/ticket/406 is
PHP SCRIPT_NAME, PATH_INFO, PHP_SELF and others improperly
converted to lowercase
What is the relation between the code and the ticket#406? some typo?

I've already answered this whole thing. Try searching the group. :-)
