I've configured IIS to act as a reverse proxy for a development server (dartlang's pub serve if you're curious). I'm doing this because the development server doesn't support custom error pages and I need them to be working locally. I've set up the custom error page in IIS but it's not serving it -- it's passing through the default 404 page from the source server. Is it possible to make the reverse proxy serve it's own custom page for 404 errors?

Late to the party, but here you go: when using IIS 7+ as a reverse proxy, you can configure it to use its own error pages (custom or otherwise) by adding the following to web.config:
<system.webServer> <httpErrors existingResponse="Replace"/> </system.webServer> More info in the docs...
