 We already have a length check on the total request: half the workspace.
 That should probably become a parameter. Further checks should be in VCL,
 and while it is easy to do
  if (length(req.http) > 200) {...}

 it is harder with req.http.* since you may not know which headers are
 there. A combination with a header-washing function is relevant here.

 I have moved this to the PostTwoShoppingList wiki page.
