Notes/Domino 6 and 7 Forum : IIS / Domino on same box

I have searched the forum and there is plenty on this topic which has helped a lot. Thanks. However, it still hasn't completely solved my problem ...

I want to run IIS on port 80 and Domino on a different port, I've chosen 1080.

I successfully get the default IIS page if I connect from my browser using the IP address, say:

http://192.168.13.100

I also successfully get served pages from Domino if I stipulate port 1080, say:

http://192.168.13.100:1080/log.nsf

However, if I try and access the Notes Log via IIS it doesn't work and the browser prompts as if I am trying to download the file.

The Websphere plugin is working and correctly matches the ".nsf" in the URL, see excerpt from the plugin log:

websphereVhostMatch: Comparing '*:-1' to '192.168.13.100:80' in VhostGroup: default_host
websphereVhostMatch: Found a match '*:-1' to '192.168.13.100:80' in VhostGroup: default_host
iis_plugin: checkRequest: WebSphere will handle: /Log.nsf
iis_plugin: checkRequest: Adding header: x-ibm-incoming-enc-url: /Log.nsf
iis_plugin: checkRequest: Adding header x-ibm-incoming-url: /Log.nsf
iis_plugin: HttpFilterProc: In HttpFilterProc for SF_NOTIFY_LOG

However, nothing shows up in the DomLog.nsf so it appears that IIS is not passing to Domino after all.

I've also tried to get IIS to talk to Domino on a different box on port 80 this time but same result.

Can anyone help me out? Thanks.
