Adding headers to proxied requests in IIS7

Question

Hi everyone,

We are using IIS7 UrlRewrite and wish to proxy a URL to another URL, but also adding a header en-route, so that SSO will work properly in the target.

We want to add a header called Jespa-Connection-Id to a proxied request. The value for this would be: {REMOTE_ADDR}e:{REMOTE_PORT}e

This value is not being passed through, instead a very similar value is available in x-forwarded-for.

What we have currently is this inbound rule set: http://skitch.com/amitkoth/d5y3h/10.167.1.54 and this outbound rule set: http://skitch.com/amitkoth/d5y39/10.167.1.54

Is there anything else we need to do to add that header through to the proxied connection?

thanks in advance, Amit
