We've seen another post on the forum with reference to this.

The posts show that it happens due to a bug in the HttpyProxyServlet, which was to be fixed in the 6.5.2 release.

contentLengthHeader.toExternalForm()

Can you please let us know if this was accomplished and if we just replace the existing class file, with the one from 6.5.2 version, the above exception should get resolved.

Thanks in Advance,

This fix is present in 7.0 beta, available on the Isomorphic blog.

Can we try to just replace the HttpProxy class and go ahead.
