We need to single-quote string literals when they are arguments to an Erlang function. What is Erlang? Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. Parses a URI. If no scheme defaults are provided, the value of the scheme_defaults function is used. When parsing a URI with an unknown scheme (that is, a scheme not found in the scheme defaults), a port number must be provided, otherwise the parsing fails.

Trials and validations. Input validation made me wonder if I should have asked for a second coffee. Please note that httpc normalizes input URIs before internal processing and special care shall be taken when the URI has percent ("%") characters. A percent serves as the indicator for percent-encoded octets and it must be percent-encoded as "%25" for that octet to be used as data within the URI. Hi I'm new to Erlang so please forgive my ignorance.
