This is possible but slightly tricky because ibrowse implicitly adds the Content-Length header to the request if it is not specified by the caller. Is this a feature which is really required? In other words, how badly do you want it :-)
I'm going to close this for now as there isn't much demand for this feature.
lhttpc supports this, there is probably no demand b/c people who need binaries in HTTP headers will probably use other HTTP clients instead of ibrowse.
Fair point, I didn't know that.
Fixed in 8d9ccc7 on the master branch
