IntrFilt Click Map Support
Click map support is provided directly from within the IntrFilt filter program.
Support is provided for
CIRC, CIRCLE, RECT, and POINT. POLY is not currently included (I havn't had
time to port the code
from Don Meyers' script!).
Click maps are currently identified from the file suffix ".map" in the URL,
i.e. the map file must be in the
directory addressed by the URL. There is currently no map alias file
implementation, nor translation of
cgi-bin/IMAGEMAP requests.
The map file is a text file. Blank line and comment lines starting with"#"
are ignored. Each line should
start with a keyword, "DEFAULT", "RECT", "CIRC", "CIRCLE", "POLY" or "POINT"
followed by the
appropriate coordinates and the redirection URL:
- DEFAULT default URL
- RECT URL X1,Y1 X2,Y2 Where X1,Y1 are the coordinates of one corner, and
X2,Y2 are
the coordinates of the diagonaly opposite corner.
- CIRC URL X,Y X2 Where X,Y is the centre point, and X2 is the length of
the radius
- CIRCLE URL X1,Y1 X2,Y2 Where X1,Y1 are the coordinates of the centre,
and X2,Y2 are the
coordinates of any point on the circumference.
- POLY URL X1,Y1 X2,Y2 ...Xn,Yn Where each Xn,Yn pair are the coordinates
of a vertex
(corner) of the shape.
The resulting URL is returned to the client as a redirect instruction.
NOTE Redirection always adds the
server name (localhost ) if no server is specified
in the URL.
