How To Disable Caching for all HTTP Requests in Quarkus 📎
Cache-Control: no-cache, no-store, must-revalidate
Pragma: no-cache
Expires: 0
quarkus-undertow extensions first:
mvn quarkus:add-extension -Dextension="quarkus-undertow"
With the added extension, Quarkus understands the "Undertow Predicate Language", which can be
used to manipulate the HTTP request and responses. Quarkus expects the configuration file: undertow-handlers.conf to be located in src/main/META-INF
(same directory as application.properties).
The built-in Disable Cache Handler with the name disable-cache already sets all the necessary headers.
Caching of all GET-requests (JAX-RS, Servlet and static content), can be disabled with the following line in undertow-handlers.conf:
method(GET) -> disable-cache
Now curl -i localhost:8080 generates the following output:
HTTP/1.1 200 OK
Cache-Control: no-cache, no-store, must-revalidate
Pragma: no-cache
