Some related thoughts:
<br>
<br>
- related ticket for configuring default WMS version:
<a class="moz-txt-link-freetext" href="http://trac.osgeo.org/mapserver/ticket/3444"><a href="http://trac.osgeo.org/mapserver/ticket/3444">http://trac.osgeo.org/mapserver/ticket/3444</a></a> ...please add yourself
to the CC list of that ticket and join in the discussions and
testing and feedback, thanks

I added myself in the cc list. The description of that ticket says
"For example in WMS if the version parameter is not set, <a class="wiki" href="http://trac.osgeo.org/mapserver/wiki/MapServer">MapServer</a>
usually defaults to the latest supported version (1.3.0)." If I
read this correctly, if I change MapServer from 5.2.x to 5.6 and I
happen to be working with EPSG codes that have their axes flipped
between 1.1.1 and 1.3.0, my WMS requests won't work anymore IF i
didn't specify a version number. Ouch. <br>
<br>
Also, what happens if I specify a non existent, but valid, number
like 1.2222 ? I know an image is an image as Jukka mentioned, but
how do I know how MapServer interpreted my faulty version number ?
Does it default to the latest supported version too ?<br>

...specifically see the 2 working 1.3.0 example requests there

I've seen those. I can see the request parameters all right, it's
just that I'm not sure how MapServer reacts. I know it chokes if I
send VERSION=abc, but it will send me an image whatever I use for a
version number as long as it is of the forms x.y or x.y.z.
VERSION=1234.4567.890 will work ! Because I get only an image back,
how do I know how MS handled the request ? Is there a response
header I'm missing somewhere ?<br>
<br>
Thanx.<br>
