|
// 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 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. To allow XMLHttpRequest calls from a local URL to all
|
|
// origins set the CefSettings.universal_access_from_file_urls_allowed value
|
|
// to true.
|
|
//
|
|
// If |is_display_isolated| is true 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.
|
|
//
|

// per unique |scheme_name| value. If |scheme_name| is already registered or

// if an error occurs this method will return false.
