I assuming that
mayApp: may be a typo where mayApp is meant to be myApp. Please forgive my ignorance in this area. However, neither of these seem to be recognized by standards.
You can find most if not all recognized URI schemes here:
A URI scheme is the top level of the uniform resource identifier (URI)
naming structure in computer networking. All URIs and absolute URI
references are formed with a scheme name, followed by a colon
character (":"), and the remainder of the URI called (in the outdated
RFCs 1738 and 2396, but not the current STD 66/RFC 3986) the
scheme-specific part. The syntax and semantics of the scheme-specific
part are left largely to the specifications governing individual
schemes, subject to certain constraints such as reserved characters
and how to "escape" them.
URI schemes are frequently and incorrectly referred to as "protocols",
or specifically as URI protocols or URL protocols, since most were
originally designed to be used with a particular protocol, and often
have the same name. The http scheme, for instance, is generally used
for interacting with web resources using HyperText Transfer Protocol.
Today, URIs with that scheme are also used for other purposes, such as
RDF resource identifiers and XML namespaces, that are not related to
the protocol. Furthermore, some URI schemes are not associated with
any specific protocol (e.g. "file") and many others do not use the
name of a protocol as their prefix (e.g. "news").

It is likely that the browser you are using does not recognize the URI scheme you are trying to reference and therefore does not support it.
