MHTML, MIME-HTML, is a webpage format that can combine different resources, such as text, images, flash, audio or much more in one file.
In MHTML, the combination of resources such as text, images, flash, etc. can be achieved on through the use of MIME multipart/related content type.
MHTML defines the naming of objects that are normally referred to by URLs and the means of aggregating resources that go together. Two MIME headers, Content-Location and Content-Base, are defined in order to resolve references to other content stored locally in related body parts. Content-Base gives an absolute URL base, or "starting point",for relative URLs that appear in other MIME headers and in HTML documents that do not contain any BASE HTML elements. Content-Location specifies the URL that corresponds to the content of the body part that contains this header.
MHTML is commonly used in emails.
