[ms4w-users] mr sid

[Jeff McKenna]

Kevin,

(please always reply to the MS4W list please)

Old MS4W archives are available at http://dl.maptools.org/dl/ms4w/)

Note that ms4w-2.1 is in the PHP5 stream (and that the PHP4 stream, 1.x, 
no longer "flows").  You might be looking for version 1.5.5

Version 2.2.2 is recommended however, since 1.5.5 is so old (and 
unsupported).
