添加新的HTTP和HTTPS绑定后，WCF停止在IIS 7上工作

Question

I am using ASP.NET 3.5 with C# . I have a web-application that have a WCF . I had deployed it on Server with Bindings HTTP and HTTPS . Everything was working well.

Today I added two more bindings of HTTP and HTTPS on the same site but with different host names . (I have that new domain registered and I already have pointed that with my IP address). And suddenly, the WCF for that same site stopped working.

I did it for two sites in IIS and both of them are returning exception on WCF call, however the login and all other pages are working fine.

The ServiceModel part of web.config is as below :

     <system.serviceModel>
        <bindings>
            <webHttpBinding>
                <binding name="webBindingHTTP">
                    <security mode="TransportCredentialOnly">
                        <transport clientCredentialType="None" />
                    </security>
                </binding>
                <binding name="webBindingHTTPS">
                    <security mode="Transport">
                        <transport clientCredentialType="None" />
                    </security>
                </binding>
            </webHttpBinding>
        </bindings>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true">
        </serviceHostingEnvironment>
        <behaviors>
            <endpointBehaviors>
                <behavior name="ihrole.service.remoteBehavior">
                    <webHttp />
                </behavior>
                <behavior name="webHttpEnabled">
                    <webHttp/>
                </behavior>
            </endpointBehaviors>
            <serviceBehaviors>
                <behavior name="ihrole.service.remoteBehavior">
                    <serviceMetadata httpGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <services>
            <service behaviorConfiguration="ihrole.service.remoteBehavior" name="ihrole.service.remote">
                <endpoint address="" behaviorConfiguration="ihrole.service.remoteBehavior" bindingConfiguration="webBindingHTTP" binding="webHttpBinding" contract="ihrole.service.Iremote" />
                <endpoint address="" behaviorConfiguration="ihrole.service.remoteBehavior" bindingConfiguration="webBindingHTTPS" binding="webHttpBinding" contract="ihrole.service.Iremote" />
            </service>
        </services>
    </system.serviceModel>

Again, I do have another site hosted on the same IIS that is also having HTTP and HTTPS bindings. But I haven't added the new ones in this site and the WCF call is working fine on the same.

Any guess or solution? Thanks in advance..

Here you need to specify that your WCF service can be run on all Bindings for a single website.

In Asp.Net 3.5, when a website has multiple bindings, you should specify Pass through filters ( adding a base address for the WCF service ) using the <baseAddressPrefixFilters> element. See Sample below. MSDN reference here.

<system.serviceModel>
    <serviceHostingEnvironment>
    ... 
        <baseAddressPrefixFilters>
            <add prefix="http://Testsite2.com:3546"/>
            <add prefix="http://testSite.com:3566"/>
        </baseAddressPrefixFilters>
   ...
    </serviceHostingEnvironment>
</system.serviceModel>

So, here http://Testsite2.com:3546 and http://testSite.com:3566 are the only base addresses, for their respective schemes, which will be allowed to be passed through, which means simply that WCF service will work for these two addresses. The baseAddressPrefixFilter does not support any wildcards .
