java.lang.Object
  no.sesat.search.http.filters.MD5ProtectedParametersFilter

All Implemented Interfaces:

Filter

public final class MD5ProtectedParametersFilter
extends Object
implements Filter

Generalised way to protect parameter values through md5 signings. A skin must define the properties (in configuration.properties): md5.secret and md5.protectedParameters Any secret can be chosen. Any parameter matches those listed in md5.protectedParameters (separated by commas) are expected to have a paired parameter (called <parameterName>_x) that represents the signing of the original parameter value. If this second parameter does not exist or it's not an accurate signing of the original parameter then the request immediately returns with a 404 response error.
