Perl updating zone files
Have you ever gotten tired of having to change both the forward and reverse zone maps when adding, removing, or changing hosts in DNS? mkrdns automates the tedious procedure of editing both forward and reverse zones when making changes to your zones with likely no changes to your current configuration file.mkrdns does this by reading through all of the primary/secondary (master/slave) zones in your configuration file (either or named.conf).It will then automatically generate the reverse zone entries (IN PTR) for the networks for which you are the primary/master.It is now possible to simply edit the forward map, run mkrdns, and reload the zone. This may let the user include one or more files into the form submission.The form is often processed so that such files are stored onto the disk of the Web server; this is why file input (or file submission) is often called “file upload.” File input opens interesting possibilities, but browser support is still limited and generally of poor quality even in newest versions.Moreover, users are often puzzled with it, since most people use file input rather rarely.
The definition must be rigorous, since otherwise it is impossible to process the data in a useful, robust way by computer programs.
The HTML specification defines two possible values for structure means that each file comes in a nice “package” inside a larger package, with a suitable “label” (content type information) on the inner “package.” This type was originally defined in RFC 1867 but it is also discussed in RFC 2388 (see notes on the RFCs later).
Normally you should not try to re-invent the wheel by writing code which interprets (decodes) the encoded form data.
Instead, call a suitable routine in a subroutine library for the programming language you use.
It typically decodes the data into a convenient format for you to process in your own code.
