We've got a lot of JQuery code that calls back-end web services, and we're worried about exposing the web services to the outside world - anyone can "view source" and see exactly how we're calling our web services. Are there any suggestions or guidelines regarding protecting one's source from such disclosure? Thanks in advance!
If the details have to be in the JS (really?) then accept that they have to be exposed to all and sundry and design to that constraint (which may mean deciding that you really don't want to drink the web 2.0 Kool-Aid after all...). There are all manner of weaselly described/advertised code "encryptors" and such, which are really just obfuscators. If the code has to run in the (JS interpreter of the) client browser, it is necessarily available to any marginally competent "attacker" (or even me). Anyone motivated enough (and that will not have to be terribly motivated) will be able to untangle the results of such and then try to make sense of the remaining representation of your code.
