+      Capsule will load and serve this wasm module,
+      but in the same process. It means that if you want to update the `index.page.wasm` module,
+      you will need to stop and start again the Capsule HTTP process.
+
+      There is another solution:
+      - start the capsule http without any file
+      - start a function name `index.page` (as any other function)
+      Then, you will be able to redeploy a version of `index.page`
