The following URL is the release notes from GoAhead. http://data.goahead.com/Software/Webserver/2.1.4/release.htm I have only done a minimal amount of testing (i.e. the network demo program works fine). Please try this out and let me know if it works. The patch needs to be applied on the c/src/libnetworking/rtems_webserver directory.
