Some updates: It turns out that if using mod_proxy, the setting to change is *responsefieldsize. *It needs adding to the *ProxyPass* of the apache configuration, e.g.
ProxyPass / http://localhost:4000/ responsefieldsize=12392 In case it helps others seeing the same issue. Increasing this to a very large number does not seem like a very secure option. Would it be possible for the signposting feature to include a configuration setting to limit the number of links added to the header?
