Sails looking in wrong directory - node.js

Question

I'm new to sails.js and node.js, so the question might be trivial, but I couldn't find the answer. I have deployed my node.js app to a web site in IIS, so the app can be reached at http://example.com/myapp/. When browsing to http://myhost.com/myapp/app.js, I get http status 404 (Not found), because sail.jss is looking for URLs like http://myhost.com/images/logo.png, but this file is in fact located at http://myhost.com/myapp/.tmp/public/images/logo.png. This .tmp folder seems to be created on the fly by the framework.
Can someone shed some light on this?
[edit]
I have added rewrite rules in the web.config and it works much better. But it only works if I put the application at the root of my web site (acessing http://myhost.com/). If I put the application in a lower level (accessing through http://myhost.com/myApp), then the added rules do not seem to produce any effect.
Here is the web.config:
<handlers>
<add name="iisnode" path="app.js" verb="*" modules="iisnode" />
</handlers>
<rewrite>
<rules>
<rule name="StaticContent">
<action type="Rewrite" url="assets{REQUEST_URI}"/>
</rule>
<rule name="DynamicContent">
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>
</conditions>
<action type="Rewrite" url="app.js"/>
</rule>
</rules>
</rewrite>

The key is to allow Express to handle all of the routing. The best way to do that is to route all traffic to app.js via iisnode (from: https://nodestream.wordpress.com/2015/11/24/sails-js-configuration-for-iis/):
<configuration>
<system.webServer>
<!-- Tell IIS to use the iisnode module to run your
application -->
<handlers>
<add name="iisnode" path="app.js" verb="*" modules="iisnode" />
</handlers>
<!-- Add iisnode with the #nodeProcessCommand line if
you see the error: Make sure the node.exe executable
is available at the location specified in the
system.webServer/iisnode/#nodeProcessCommandLine element
of web.config. -->
<iisnode
nodeProcessCommandLine="%ProgramFiles%\nodejs\node.exe"
/>
<!-- Since behind the covers, Sails.js is just an express app
rewrite all urls to processed by iisnode via app.js. This
will sort out things like the routing to your public
resources (images, js, styles) and all configured rest
endpoints. -->
<rewrite>
<rules>
<rule name="root">
<match url=".*" />
<action type="Rewrite" url="app.js" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>

Well the .tmp folder is created by Grunt. You can reference the gruntfile and the task folder. The pipeline.js allows you to select files/folders for grunt to inject and spit out. You can easily change this to point to /images and /js folders.
tasks/pipline.js
module.exports.cssFilesToInject = cssFilesToInject.map(function(path) {
return '.tmp/public/' + path; // Change this
});
module.exports.jsFilesToInject = jsFilesToInject.map(function(path) {
return '.tmp/public/' + path; // Change this
});
Another solution I could think of, however I am not sure if IIS has it, is to do a rewrite rule. When a user goes to site.com/images, point them to .tmp/public/images. It is common to see that in Apache servers.
