Examples

ICONURLPREFIX helps in maintain relative-based archives that use icons. For example, we have a file called icons.mrc which has the following ICONS setting:

<Icons>
application/*;[20x22]generic.gif
application/postscript;[20x22]ps.gif
application/octet-stream;[20x22]binary.gif
application/pdf;[20x22]pdf.gif
application/zip;[20x22]compressed.gif
audio/*;[20x22]sound1.gif
chemical/*;[20x22]sphere2.gif
image/*;[20x22]image2.gif
message/external-body;[20x22]link.gif
multipart/*;[20x22]layout.gif
text/*;[20x22]text.gif
video/*;[20x22]movie.gif
*/*;[20x22]generic.gif
</Icons>

All the icon URLs are specified by their basename. Now, for the various archives, we specify icons.mrc, but then define ICONURLPREFIX to give the relative location of the archive to the icon files:

prompt> mhonarc -rcfile icons.mrc -iconurlprefix ../icons/ ...

And another archive may have:

prompt> mhonarc -rcfile icons.mrc -iconurlprefix ../../icons/ ...

The use of ICONURLPREFIX avoids the need to redefine the ICONS resource for each archive and helps support archive relocatability. For example, if the archives were to be copied to a new server under a different URL root, we avoid regeneration of the archives since the URLs used for icons is relative and not absolute.
