WCF, Metadata and BIGIP - Can I force the correct url for the WSDL items?
- by Yossi Dahan
We have a WCF service hosted on ServerA which is a server with no-direct Internet access and has a non-Internet routable IP address.
The service is fronted by BIGIP which handles SSL encryption and decryption and forwards the unencrypted request to ServerA (at the moment it does NOT actually do any load balancing, but that is likely to be added in the future) on a specific port.
What that means is that our clients would be calling the service through https://www.OurDomain.com/ServiceUrl and would get to our service on http://SeverA:85/ServiceUrl through the BIGIP device;
When we browse to the WSDL published on https://www.OurDomain.com/ServiceUrl all the addresses contained in the WSDL are based on the http://SeverA:85/ServiceUrl base address
We figured out that we could use the host headers setting to set the domain, but our problem is that while this would sort out the domain, we would still be using the wrong scheme – it would use http://www.OurDomain.com/ServiceUrl while we need it to be Https.
Also – as we have other services (asmx based) hosted on that server we had some issues setting the host headers, and so we thought we could get away with creating another site on the server (using, say, port 82) and set the host header on that; now, on top of the http/https problem we have an issue as the WSDL contains the port number in all the urls, where BigIP works on port 443 (for the SSL)
Is there a more flexible solution than implementing Host Headers? Ideally we need to retain flexibility and ease of supportability.
Thanks for any help…
