How do you prevent HttpWatch from interpreting javascript single-line comment as call to a missing resource thus resulting in a 404 error?
Perhaps you should ask the HttpWatch-guys? This has nothing to do with javascript.
I think it thinks that the //…
is intended to be a relative URI just without the scheme.
HttpWatch doesn't interpret the javascript - it just records the HTTP traffic generated by the browser. Any 404 error that you see is merely being reported by HttpWatch not generated by it.
If you can provide a .hwl file from HttpWatch or a public URL where this occurs we'll have a look to see why the 404 is generated.

The original poster could be referring to the invalid URL http://:/ appearing in the HttpWatch log. This is a side effect of a commonly used technique in javascript libraries that attempt to emulate a DOMContentLoaded event in IE:
