MaxURL length in WCF Self Hosted Service

Question

I have a self-hosted WCF REST service that is configured in code that does not use

an app.config or web.config file.  I need to change the MAX URL Length since some

of the URLs I am using (WebGet Only) are longer than 2Kb.  I have tried all the

MaxReceivedMessage size, etc. settings to no avail.  Any ideas ?
