Can't open ECW files from an image web server

[daniel112@…]

I'm having trouble reading ECW files from an image web server. 

gdalinfo ecwp://www.earthetc.com/images/usa/1meterCalif.ecw

returns:

ERROR 4: `ecwp://www.earthetc.com/images/usa/1meterCalif.ecw' does not exist in
the file system,
and is not recognised as a supported dataset name.

I think that it is due to the change made in ecwdataset.cpp Rev 1.12

   if( !EQUAL(CPLGetExtension(poOpenInfo->pszFilename),"ecw")
        || poOpenInfo->fp == NULL )
   return( NULL );

poOpenInfo->fp seems to be NULL (not suprisingly) when accessing an image web
server, removing that condition makes it work.

Fixed.

There are now two cases properly supported:
 o Regular files ending  in .ecw
 o any name prefixed with ecwp:
