Zoran, It looks like you are using Proj4js where it dynamically loads the required projection code files. In some earlier versions of Proj4js that had problems in IE (possibly in Chrome as well) but I think that is fixed in the latest version. In any case, you can get around the issue by

That error is normal and expected. What happens is that proj4js first tries to load the projection definition from the local server and if it can't find it (that's the error you see) it will try to look it up from spatialreference.org. However to do that you need to define a proxy script

Yes cscs did have that problem. However the Proj4js version loads only the projection class code required based on the projection definition so you never need to worry about that. If you know beforehand what projections your app will be dealing with, you can also load the code statically.
