The first activity when loading a page is to 'fetch' it. 'Fetching' a Logiweb page is a process which takes a Logiweb reference as input and produces a Logiweb vector as output.
A Logiweb vector is a sequence of bytes. The vector of a Logiweb page is the form in which Logiweb pages are stored on disk and transmitted over networks.
A Logiweb vector must either conform to the Logiweb default format or to a user defined format. In the latter case, an advanced Logiweb user must tell Logiweb how to unpack that format. As an example, one may explain Logiweb how to interpret pfb font files. After that, Logiweb can handle such files, but the files have to be prepended with about 70 bytes (two references and a dictionary) which identify the format before submission to Logiweb.
Fetching a page consists of 'locating' and 'getting' the page. 'Locating' a page is a process which takes a Logiweb reference as input and produces a uniform resource locator (url) as output. 'Getting' a page is a process which takes the url as input and produces the vector as output.
