How to make your own etag

The Webapp and Android app had similar requirements. Previously they provided caching using a versions API that would keep track of any modifications made to Events or Services.

The response of the API would be something like this: So when the client user starts his app, the app would make a request to the versions API, check if it corresponds to the local cache and update accordingly. It had some shortcomings, like checking modifications for a individual resources.

And if a particular service microlocation, track, etc.

This hash, called the ETag is sent with the response to the client, preferably as a header. The client then caches the response data and the ETag alongside the resource. Next time when the client makes a request at the same endpoint to fetch the resource, he sets an If-None-Match header in the request.

This header contains the value of ETag the client saved before. The server grabs the resource requested by the client, calculates its hash and checks if it is equal to the value set for If-None-Match. If the value of the hash is same, then it means the resource has not changed, so a response with resource data is not needed.

If it is different, then the server returns the response with resource data and a new ETag associated with that resource. Flask-Restplus includes a Resource class that defines a resource.

It is a pluggable view. Check only for GET requests, for now. Resource has not changed return '', else: Then hash for the resp response is calculated.

If they are not equal, then a normal response is sent with the new value of ETag. Thu, 21 Jul Since the hash is calculated for every GET request it increases the load on servers.

So if four clients request the same resource, the server calcuates hashes four times. This can be solved by calculating and saving the ETag during creation and modification of resources, and then getting and sending this ETag directly.When I make a request to this endpoint, I get the following - my Cache-Control headers look great, but no ETag: If anyone can point me in the right direction for why this ETag isn't being applied, I'd certainly appreciate it!

In this case, an etag might make sense to allow the client to use cached data most of the time but be able to refresh its data if you touch up or edit the photo.

On the other extreme, if you are serving lots of smaller files (e.g. images, HTML, javascript files - a typical website in other words), the overhead of making a request to check the. Having said that, it is very easy to implement your own and we will look into this further down in this post (I have chosen LMDB, a super fast file-based storage by Howard Chu).

This was explained in the previous post, but essentially representation's ETag (or Last-Modified) header gets used to validate the cached resource with the server. ETag based caching for GET APIs The concept of ETag (Entity Tag) based caching is simple.
