support for setting baseurl to "/plexivity" to allow reverse proxing

can you provide some more info on that?

After some diggin around I found a way which gives you partial support for having a reverse proxy, but @Raphael needs to update a few links to make it work 100%. A few things I noticed was The setup submit button needs to be changed and the history page doesn't load (there are some ajax errors)..

In app/__init__.py under the line:

from flask.ext.restless import APIManager, ProcessingException

add

class ReverseProxied(object):
    '''Wrap the application in this middleware and configure the 
    front-end server to add these headers, to let you quietly bind 
    this to a URL other than / and to an HTTP scheme that is 
    different than what is used locally.

    In nginx:
    location /myprefix {
        proxy_pass http://192.168.0.1:5001;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Scheme $scheme;
        proxy_set_header X-Script-Name /myprefix;
        }

    :param app: the WSGI application
    '''
    def __init__(self, app):
        self.app = app

    def __call__(self, environ, start_response):
        script_name = environ.get('HTTP_X_SCRIPT_NAME', '')
        if script_name:
            environ['SCRIPT_NAME'] = script_name
            path_info = environ['PATH_INFO']
            if path_info.startswith(script_name):
                environ['PATH_INFO'] = path_info[len(script_name):]

        scheme = environ.get('HTTP_X_SCHEME', '')
        if scheme:
            environ['wsgi.url_scheme'] = scheme
        return self.app(environ, start_response)

then under

app = Flask(__name__)

add

app.wsgi_app = ReverseProxied(app.wsgi_app)

Now in nginx make a location something like..

location /plexivity {
        proxy_set_header X-Script-Name /plexivity;
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-Host $proxy_add_x_forwarded_for;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_connect_timeout 60;
        proxy_read_timeout 60;
        proxy_pass        http://localhost:8000;
}

Thanks, i have currently a lot of stuff todo but i'll definitively check this out!

The History page most likely doesn't load because it requests /load/histroy which would become plexivity/load/histroy when you'll use a proxy... i think that could be fixed easily by passing the script name variable to the template engine as well :)

[Raphael Mutschler]

@wingmannz @onedr0p i've implemented this in the latest development branch, can you test and verify?

[Devin Buhl]

Thanks!! I'll give it a shot tomorrow, after a brief overview of the commits I believe there shouldn't be any issues unless you missed any other urls ;)

[Devin Buhl]

A few issues issues I've noticed from a fresh install:

in app/templates/setup.html the form url should be this:

        {{ render_form(form, action_url=url_for('setup'), action_text=_('Create Account'), btn_class='btn btn-plex') }}

and in app/templates/settings.html the form url should be this:

            {{ render_form(form, action_url='settings', action_text=_('Save settings'), btn_class='btn btn-plex') }}

Note: they are missing the preceding slash.

Other that those 2 issues I've only had a few redirect issues when trying to do a fresh install thru the proxy, which you can remedy by actually going to the URL if the page 404s or redirects to a non existent page.

I'm going to let the app run for awhile and see if I notice anything else that might be an issue. Sadly I don't have any data to work with yet. :/

@onedr0p thanks for the reply, i've fixed the 2 URL`s

[Raphael Mutschler]

new version is out and should be working

[sea3pea0]

So I got this mostly working on apache:

<Location /plexivity>
RequestHeader set X-Script-Name /plexivity
RequestHeader set X-Scheme https
ProxyPass http://localhost:[port]
ProxyPassReverse http://localhost:[port]
</Location>

It works pretty flawlessly except for the logout button. If I click logout from the main page I am redirected to the root of my webserver, for example "http://mysite.com". If I am on any of the other pages such as history or charts when I click logout, I am redirected to "http://mysite.com/history" and of course in this situation I get a 404 page not found. Anybody have any tips on a better way to set up this reverse proxy on apache?
