possibility for wrong file in Loris cache using customized HTTP resolver #524
Description
Greetings,
we are using customized Loris IIIF server on latest version 3.2.1 with custom HTTP resolver, which is downloading images to HTTP cache with our prefix. Loris cache name directories are also customized + after saving to JPG it is enhanced by PyExiv2 from the downloaded one.
We are using image server for our aplication, which can takes a lot of requests for images, but there is chance to happen, that the image stored in Loris cache can be from completely different request. It was happening in the previous Loris2 version, but I noticed that same issue in latest version. In HTTP cache, the images is OK, but the problem can happen on Loris cache - for example default.jpg or info.json in the correct possition, but from different request. How is this possible? It is not happening usually but like 2% of requests. We are using latest modules from requests.txt. Also dont know, if its causing Apache2. We are using default configuration with 10 processes and 15 threads. Can be this fixed with using single process and thread for Apache2?
