Hi Sowmya,
You're almost there. The last issue you're having (i.e. WMS 1.3.0
returning an empty map) is probably related to the coordinate order in
the BBOX param of your WMS 1.3.0 request.
You're not the first to be hit by this "feature" of WMS 1.3.0. Welcome
to the club! :-)
A more complete explanation is available here:

Hi Daniel,
Thanks for your reply. Now , I understand the difference.
I kept the version number as 1.1.1 for the WMS layers ( i.e Mapserver is acting
like a client here and it is making a 1.1.1 version WMS call)
- Now , I am making a WMS call to my mapserver which is acting like a server
with 1.3.0 specification : It does not throw any error , but I also do not see
any output. If I go in to the log file and look, I see that it has not made any
WMS call to retrieve the WMS layer I was requesting for.

Subject: Re: [mapserver-users] FW: GetCapabilities always returning version
1.3.0

Hi Rahkonen,
Thank you very much for your explanation. I know understand how it is working.
But, I am still confused about why it is not working when I make a call with
1.3.0 specifications.
I am getting this error : "msBuildWMSLayerURL(): WMS connection error. Map Server
supports only WMS 1.0.0 to 1.1.1 (please verify the VERSION parameter in the connection
string)."
But the GetCapabilities returns the default supported version as 1.3.0. Any
more suggestions on ideas on why this is happening will be greatly appreciated.
Thanks,
Sowmya.
You seem to be mixing two things:
1- The error above is returned by the CONNECTIONTYPE WMS code (i.e.
using MapServer as a WMS client) which is indeed supported only for WMS
1.0 or 1.1. This error message could definitely be improved to make it more
obvious that it applies only to CONNECTIONTYPE WMS.
2- The GetCapabilities is MapServer acting as a *server* for other remote
clients, and in this case 1.3.0 is supported.
I am not sure what you are trying to achieve (I missed the beginning of the
thread), but you should probably take a few minutes to re-read Jukka's
explanation in light of the two points above.
