Since upgrading on 2.10.1 (previously on 2.9.1) a regression appeared :
- the first call on WMS GetCapabilities (without “If-None-Match” header) is ok
- the second call on WMS GetCapabilities (with “If-None-Match” header set to previous request response ETag) fail with a 404 error code.
All major browsers set “If-None-Match”, so every second call from a brower fails.
After some tests we concluded that GetCapabilities fails only when a “If-None-Match” header is set to a valid Etag returned by a previous call to geoserver GetCapabilities. It seems to be linked to the GetCapabilities cache.
Geoserver log this stack :
