See Uniteness for better way to handle URLs.

Basically URLs that you can use are fixed format:
[computer_name] is the name you gave your computer when installing Opera Unite.
[your_opera_login] is the login to your Opera account.
[application] is the name of the service defined in config.xml.
[page] is what you define below:

Brackets ([]) added for clarity, URLs don't include those.

Then you define in your service:
window.onload = function () {
    webserver =
    if (webserver)    {
        webserver.addEventListener('_index', start_page, false);
        webserver.addEventListener('other', other_page, false);
        // webserver.addEventListener('_request', all_requests, false);
        // webserver.addEventListener('_close', onunload, false);
        // [1]
function start_page(r) {    // http://..../[application]/
   // ....

function other_page(r) {    // http://..../[application]/other/
   // ....
start_page will be called at
other_page will be called at

If you enable '_request' - any request will call that (see below for "User-friendly URLs").

Don't forget to enable webserver library in your config.xml.

In Uniteness

    '_index', start_page,
    'edit', edit_item,
    'imgs', 'static',

User-friendly URLs

It seems somewhat user-friendly URLs are POSSIBLE. Digging request hierarchy I've discovered variable:
r.connection.request.uri = "/[service_path]/delete?get_param=get_value"
The "/[service_path]/delete?get_param=get_value" is the analogous to $_SERVER[REQUEST_URI] in PHP, which means you can process it yourself.

You need to hook into '_request' URL instead of '_index'. [See URLs about 'hooking']

Domains (

Originally I thought that using CNAME would be possible, but after a test I have to admit that CNAMEs don't work.

You can still have a domain point to your Unite browser, but you need a registrar that supports framed domains or URL redirects. Many browsers (NameCheap and Dynadot for sure) support this option. Just setup your domain to be a redirect to your Opera Unite URL.
