  We present a new tool for precision measurements of the Higgs boson
production mechanisms at the LHC. We study events with a Higgs boson produced
with two forward jets. Even with fairly stringent cuts, one expects a
significant contamination of gluon fusion (GF) in addition to vector-boson
fusion (VBF) in the event sample. By measuring the jet energy profile of the
most central jet, we find that SM production can be distinguished from either
pure VBF or pure GF at the $5\sigma$ level with 100 fb$^{-1}$ of luminosity at
the 14 TeV LHC. Moreover, this discrimination technique can be used to validate
or rule out new physics models that predict similar observable branching
fractions as the 125 GeV SM Higgs but have different production mechanisms.
