Part 1 provides an overview of HTTP and its associated terminology, defines the &#34;http&#34; and &#34;https&#34; Uniform Resource Identifier (URI) schemes, defines the generic message syntax and parsing requirements for HTTP message frames, and describes general security concerns for implementations.">
