🕳️ Our awesome url shortener
When visiting upfra.me the Lambda function responds with an
HTTP 301 permanent redirect to upframe.io, appending any
path that the user requested.
By default the response includes a Cache-Control: max-age=604800 header to make
the browser check again for a new redirect location after one week.
Custom redirects are loaded from a DynamoDB database. These exceptions can include
a location to redirect to and override the default expiration time. If the
redirection url starts with https:// or http:// it is treated as a complete
url, otherwise it is appended as a path to https://upframe.io. The DynamoDB lookup
for any given path is cached for the lifetime of the Lambda function.
