+### Non-proxy API (legacy)
 
 This API is exposed both to mods and server-side JavaScript. This API also includes proxy requests, which don't use CONNECT method. It's possible to determine, if the request comes from the proxy, by checking if _req.url_ begins with "_http://_" or with "_https://_" (unlike non-proxy requests, for which _req.url_ begins with "_/_") like this:

 ### Client-initiated secure renegotiation
 
 Client-initiated secure renegotiation may pose DoS risks. However, Node.JS (JS runtime on which SVR.JS is running on) has built-in protection against DoS attacks caused by client-initiated secure renegotiation. Such attacks can be detected by looking for _ERR_TLS_SESSION_ATTACK_ errors in server log.

 You can configure SVR.JS to serve custom error pages by adding _.<errorcode>_ (SVR.JS 3.0.0 or newer) or _<errorcode>.html_ pages. For the 404 error, you can specify it by changing the _page404_ property in _config.json_. From SVR.JS 3.8.0 onwards, you can use _errorPages_ property in _config.json_ to specify path to each custom error page.

 ### HTTP authentication
 
 You can add HTTP basic authentication by including a 401 code (with _scode_ property set to 401) entry in the _nonStandardCodes_ property of _config.json_. To enable HTTP basic authentication, you need to specify the URL you want to restrict in the _url_ or _regex_ property of the entry. Additionally, you can set the authentication realm in the _realm_ property. If the realm is not specified, the default realm is "_SVR.JS HTTP Basic Authorization_". The encoding used for authentication will always be UTF-8.

 # Redirects
 
 Setting up HTTP redirects is simple with SVR.JS. You can add a 301 or 302 code (with `scode` property set to 301 or 302) entry to the `nonStandardCodes` property in `config.json`. The entry should specify the source URL for the redirect in the `url` or regular expression string for the redirect in `regex` property (for example `"/\\/blog($|[#?\\/].*)/"`), and the destination URL in the `location` property (for regular expressions, you can use for example `"$1"` for contents of the first capturing group). Destination location can be relative to the current site (for example `/blogs`) or a full URL (for example `https://blog.example.com`).

 ## Mods
 
 Mods in SVR.JS are custom modules that can extend the server's functionality. Using mods, you can extend SVR.JS functionality to suit your specific requirements and customize the server's behavior to handle different types of requests.

 ## Server-side JavaScript
 
 Another way to expand SVR.JS functionality is through server-side JavaScript located in _serverSideScript.js_ file inside SVR.JS web root (or locaten in SVR.JS installation directory if you're running SVR.JS 3.9.0 or newer, and you have set _useWebRootServerSideScript_ property to _false_). Server-side JavaScript allows you to create various web applications using JavaScript, Node.JS and SVR.JS API.
