Dear guilers, With the help of promises and futures, I was able to write a small caching web client for guile.
https://web-client-with-cache.planete-kraus.eu/ This is one step on my journey to write a Solid server for guile. Solid uses a decentralized authentication protocol ( https://solid.github.io/authentication-panel/solid-oidc/) which needs servers and identity providers to cache different types of files, such as openid configurations and the web profile of users and applications. The authentication protocol can be compared to the HTTP signatures used by Activitypub servers, except that Solid webid-oidc can work directly from a web browser. Solid servers themselves are required to provide web ETags for all the resources they manage, so a good client cache should understand Cache-Control headers (often used for offline caching of openid configurations) as well as the ETags. Because of the recent announce of the guile potluck on this list, combined with the recent release of guile-oauth, I thought there could be some shared interest for this subject. Best regards, Vivien
