So adding it to the EPSG file does not work? If that's the case then the
sting may be incorrect.

I can get the re-projection to work just fine, but not with a ESPG code that
is not already defined in the Proj espg file. For example I can go from my
custom coordinate system to 3857, but I cannot serve it out using my custom
code.
I think what is different about your example and mine is that in your's case
you have the EPSG code that already exists and in my case I am trying to use
a new espg number that does not previously exists.
Thanks,

List your map projection and the reprojection as above and try that.

Thanks for the reply! It looks like I have everything setup right but seems
like MapServer is not reading my espg file in the proj folder. Here's the
espg definition and here's my mapfile. Or maybe it is something with the
extent being requested with the SRS but everything looks right. I'm just
trying to display the output image in a web browser to validate it is
working.

Hi Brian, I have successfully done this as you outline below.
I checked my WMS and they reference c:\ms4w\proj\nad.
In that folder I edited the epsg file
I added the following line to the end of the file:
# ESRI Web Mercator
<102113> +proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=6378137 +b=6378137
+units=m +no_defs
Now I can serve my WMS out as Web Mercator for ArcGIS Online.

I am trying to use MapServer 6.2.1 as a WMS server with a custom projection
and espg code, but I keep getting this error message.
msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS must be
valid for all requested layers.
Is this supported? I have followed these steps.
1) Defined the custom projection with a new espg code in
\ms4w\proj\nad\epsg
2) In the mapfile, I added the reference to the Proj (CONFIG "PROJ_LIB"
"E:/ms4w/proj/nad")
3) Defined the new espg in the Web, Projection, Layer objects of the
mapfile.
4) Verified the mapfile works using the shp2img utility
Has anyone else go this to work?
Thanks!
Brian
