Hi, I am a new user of traffic server. Recently I am trying to migrate a product from ATS5 to latest ATS7. In ATS5, we use the cache feature, and use the cacheurl plugin and regular expressions to extract partial value of a query parameter to comprise the cache key. However, I didn't find corresponding feature in ATS7 cachekey plugin to get partial value of a query parameter.
For example, our request url is something like "/my/path?kw=test&geo=< country>,<state>,<city>,<street>". In ATS5, we can get "geo=<country>,<state>,<city>" (without <street>) as our cache key. However, I didn't find similar syntax to get such partial value with cachekey plugin in ATS7. https://docs.trafficserver.apache.org/en/7.0.x/admin- guide/plugins/cachekey.en.html Does anyone know how I can achieve similar feature with cachekey plugin or other plugins? Thanks, Chunlin Gong
