dynamically set WCF baseAddressPrefixFilters

Question

I have a WCF service that I am deploying in a shared hosting environment. Because of this I have to specify baseAddressPrefixFilters (see answer here for why this is necessary). Setting the base address prefix filters happens in the web.config like so...

<serviceHostingEnvironment>
  <baseAddressPrefixFilters>
    <add prefix="http://example.com"/&gt;
  </baseAddressPrefixFilters>
</serviceHostingEnvironment>

The problem is that I have multiple environments that are configured this way with their own urls (i.e. dev, test, prod)

I tried the following with no luck...

<serviceHostingEnvironment>
  <baseAddressPrefixFilters>
    <add prefix="http://dev.example.com"/&gt;
    <add prefix="http://test.example.com"/&gt;
    <add prefix="http://example.com"/&gt;
  </baseAddressPrefixFilters>
</serviceHostingEnvironment>

So the question is how do I set the baseAddressPrefixFilter dynamically at runtime?

If you are running under IIS7, this is a good walk through of the problem and solution. If not, the information for the WCF side is still what you need to know to resolve your issues.

Have you looked at the ServiceHostFactory? We used this in our 3.0 services to work with the different host headers.
