///
|
|
|
|
// Register a custom scheme. This function should not be called for the built-in
|
|
|
|
// HTTP, HTTPS, FILE, FTP, ABOUT and DATA schemes.
|
|
|
|
//
|
|
|
|
// If |is_standard| is true (1) the scheme will be treated as a standard scheme.
|
|
|
|
// Standard schemes are subject to URL canonicalization and parsing rules as
|
|
|
|
// defined in the Common Internet Scheme Syntax RFC 1738 Section 3.1 available
|
|
|
|
// at http://www.ietf.org/rfc/rfc1738.txt
|
|
|
|
//
|
|
|
|
// In particular, the syntax for standard scheme URLs must be of the form: <pre>
|
|
|
|
// [scheme]://[username]:[password]@[host]:[port]/[url-path]
|
|
|
|
// </pre> Standard scheme URLs must have a host component that is a fully
|
|
|
|
// qualified domain name as defined in Section 3.5 of RFC 1034 [13] and Section
|
|
|
|
// 2.1 of RFC 1123. These URLs will be canonicalized to "scheme://host/path" in
|
|
|
|
// the simplest case and "scheme://username:password@host:port/path" in the most
|
|
|
|
// explicit case. For example, "scheme:host/path" and "scheme:///host/path" will
|
|
|
|
// both be canonicalized to "scheme://host/path". The origin of a standard
|
|
|
|
// scheme URL is the combination of scheme, host and port (i.e.,
|
|
|
|
// "scheme://host:port" in the most explicit case).
|
|
|
|
//
|
|
|
|
// For non-standard scheme URLs only the "scheme:" component is parsed and
|
|
|
|
// canonicalized. The remainder of the URL will be passed to the handler as-is.
|
|
|
|
// For example, "scheme:///some%20text" will remain the same. Non-standard
|
|
|
|
// scheme URLs cannot be used as a target for form submission.
|
|
|
|
//
|
|
|
|
// If |is_local| is true (1) the scheme will be treated as local (i.e., with the
|
|
|
|
// same security rules as those applied to "file" URLs). Normal pages cannot
|
|
|
|
// link to or access local URLs. Also, by default, local URLs can only perform
|
|
|
|
// XMLHttpRequest calls to the same URL (origin + path) that originated the
|
|
|
|
// request. To allow XMLHttpRequest calls from a local URL to other URLs with
|
|
|
|
// the same origin set the CefSettings.file_access_from_file_urls_allowed value
|
|
|
|
// to true (1). To allow XMLHttpRequest calls from a local URL to all origins
|
|
|
|
// set the CefSettings.universal_access_from_file_urls_allowed value to true
|
|
|
|
// (1).
|
|
|
|
//
|
|
|
|
// If |is_display_isolated| is true (1) the scheme will be treated as display-
|
|
|
|
// isolated. This means that pages cannot display these URLs unless they are
|
|
|
|
// from the same scheme. For example, pages in another origin cannot create
|
|
|
|
// iframes or hyperlinks to URLs with this scheme.
|
|
|
|
//
|
|
|
|
// This function may be called on any thread. It should only be called once per
|
|
|

// unique |scheme_name| value. If |scheme_name| is already registered or if an
|
