<P><FONT SIZE=2>I don't know if this will solve your problem, but:</FONT>
</P>
<P><FONT SIZE=2>1) in your WMS request you need to use uppercase EPSG for the SRS (as defined in the WMS spec)</FONT>
<BR><FONT SIZE=2>2) in your PROJECTION blocks you need to use lowercase epsg (this is how PROJ.4, the projection library used by Mapserver, expects it)</FONT></P>
<P><FONT SIZE=2>Best regards,</FONT>

<BR>
<P><FONT SIZE=2>Hi,</FONT>
</P>
<BR>
<P><FONT SIZE=2>I am trying to use MapServer as a WMS client to another WMS (cascading WMS). </FONT>
<BR><FONT SIZE=2> The request I make is of the form:</FONT>
<BR><FONT SIZE=2><A HREF="http://localhost/cgi-bin/mapserv_44.exe?map=midas.map&version=1.1.1&request=getmap&layers=gs_lay&width=500&height=250&srs=epsg:4326&bbox=0,45,40,65&format=image/png" TARGET="_blank">http://localhost/cgi-bin/mapserv_44.exe?map=midas.map&version=1.1.1&request=getmap&layers=gs_lay&width=500&height=250&srs=epsg:4326&bbox=0,45,40,65&format=image/png</A></FONT></P>
<P><FONT SIZE=2>However, MapServer seems to do something strange to the bounding box as the </FONT>
<BR><FONT SIZE=2>box that is submitted by MapServer (as part of the getmap request) is the </FONT>
<BR><FONT SIZE=2>following:</FONT>
<BR><FONT SIZE=2>0.039999999999997732,45.019999999999996,39.960000000000001,64.980000000000004</FONT>
