Re: [Webware-discuss] "Context" Impaired - Need Help

Ray --

OK, I seem to have most of what you told me working, after a long
night's work.
Here is some of the config stuff you asked to see.  Remember, I am using
modPythonAdapter.
My directories are  /pub/httpd/tj-test              <=== this is were
Webware puts it app sub-dirs
                           /pub/httpd/tj-test/TJweb    <=== my web app
context directory


/etc/apache/httpd.conf
---------------------------
LoadModule python_module /usr/lib/apache/1.3/mod_python.so  ## for
python support

AddHandler python-program
.psp                                             ## for psp support
PythonPath "sys.path+['/usr/local/Webware/WebKit']"
PythonHandler modpHandler::pspHandler
PythonOption AppWorkDir /pub/httpd/tj-test

<VirtualHost *>
    DocumentRoot /pub/httpd/tj-test
    (other stuff here...)
        #
        # Added For WebWare / WebKit Support - rdg 7/16/02
        #
        RewriteEngine On                                          ##
solves the "/wk" problem
        RewriteRule ^(.*) /wk/$1 [L,PT]
        <Location /wk>                                              ##
location to server from
           SetHandler python-program
           # add the directory that contains ModPythonAdapter.py
           PythonPath "sys.path+['/usr/local/Webware/WebKit']"
           PythonOption AppWorkDir /pub/httpd/tj-test
           PythonHandler ModPythonAdapter
           PythonDebug On
        </Location>
</VirtualHost>


Application.config
--------------------
'Contexts':   {
                   #  'Admin':        '%(WebKitPath)s/Admin',
                   #  'Examples':    '%(WebKitPath)s/Examples',
                   #  'Docs':          '%(WebKitPath)s/Docs',
                   #  'Testing':       '%(WebKitPath)s/Testing',
                       'TJweb':        '/pub/httpd/tj-test/TJweb',
                       'default':        'TJweb',
                   },


My last questions  (ha ha ha)  ;-))

(1) Why would I have other contexts?  How would they be used/referenced
in my apps?

(2) Currently all of my web app is in the context directory.  This
includes html, psp, py, etc.
This is not what I want in the end, of course.  I probably want to put
the .py (and the resulting .pyc)
code into a different directory.  I am not sure how to implement this.

    Yes context allows one server to service multiple websites.  If you copy
    the "lines" in your httpd / apache.conf, and Application.conf line that
    you have questions about.  I can give you a better answer in relation to
    specific items.
    
    As to how to use them ( with mod_webkit, sorry don't know about
    mod_python ) ... here's a sample:
    
    [Application.conf]
    'Contexts':             {
           #'Admin':         '%(WebKitPath)s/Admin',
           #'Examples':      '%(WebKitPath)s/Examples',
           #'Docs':          '%(WebKitPath)s/Docs',
           #'Testing':       '%(WebKitPath)s/Testing',
           #'MyContext':     'MyContext',
           'rdg':        '/home/rdg/WebWareWork/rdg',
           'rdg2':        '/home/rdg/WebWareWork/rdg2',
           'default':       'rdg'
           },
    
    [apache/http.conf]
    RewriteEngine On
    RewriteRule ^/wk/(.*) /$1 [R]
    RewriteRule ^/rdg(.*) /wk/rdg/$1 [L,PT]
    RewriteRule ^/rdg2(.*) /wk/rdg2/$1 [L,PT]
    <Location /wk>
        WKServer localhost 8086
        SetHandler webkit-handler
        order deny,allow
        deny from all
        allow from localhost .localdomain
        allow from 192.168.10.
        allow from 10.0.0.
        Options Indexes FollowSymLinks
    </Location>
    
    Ok, If you have any other questions just let us know.  Hope this helps!
    
    Ray
    
    PS : I "got" most of this from using the RewriteRule's wiki page, and a
    heck of a lot of experimenting.  I only say it as a warning ... your
    results may vary, and this is meant for a Linux / *nix machine running
    mod_webkit.
