I could create an azure function proxy with success that routes requests to my blob storage. However, it only works if I specify the Backend URL with the full url to the blob file:
ex:
https://account.blob.core.windows.net/site/index.html
where '/site' is my container name and 'index.html' is my blob name.
I had an understanding that I could use the route template as '/site' and if I leave the Backend URL as 'https://account.blob.core.windows.net/site/' what comes after the last '/' would be routed to my storage account. Did I understand wrong?
UPDATE After reading this other question Azure Function App Proxy to a blob storage account and update the route template / backend url it works, but if my blob name has an extension it does not work (such as .html). Any clues?
In the Azure Functions Proxy documentation they specify how to get the request parameters and pass those to your backend service.
Your template can be /site/{*restOfPath}
And your backend would be https://account.blob.core.windows.net/site/{restOfPath}
I was able to get this working only on files that do NOT have a file extension. So I was able to add an index blob and get to it from https://myfunction.azurewebsites.net/index, however, when I tried index.html, the proxy returned a message "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."
