 ## tip
 
+* FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): allow routing incoming requests bassed on HTTP [query args](https://en.wikipedia.org/wiki/Query_string) via `src_query_args` option at `url_map`. See [these docs](https://docs.victoriametrics.com/vmauth/#generic-http-proxy-for-different-backends) and [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5878).
 * FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): reduce memory usage by up to 5x when aggregating over big number of unique [time series](https://docs.victoriametrics.com/keyconcepts/#time-series). The memory usage reduction is most visible when [stream deduplication](https://docs.victoriametrics.com/stream-aggregation/#deduplication) is enabled. The downside is increased CPU usage by up to 30%.
 * FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): allow using `-streamAggr.dedupInterval` and `-remoteWrite.streamAggr.dedupInterval` command-line flags without the need to specify `-streamAggr.config` and `-remoteWrite.streamAggr.config`. See [these docs](https://docs.victoriametrics.com/stream-aggregation/#deduplication).
 * FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `-streamAggr.dropInputLabels` command-line flag, which can be used for dropping the listed labels from input samples before applying stream [de-duplication](https://docs.victoriametrics.com/stream-aggregation/#deduplication) and aggregation. This is faster and easier to use alternative to [input_relabel_configs](https://docs.victoriametrics.com/stream-aggregation/#relabeling). See [these docs](https://docs.victoriametrics.com/stream-aggregation/#dropping-unneeded-labels).

 If both `src_paths` and `src_hosts` lists are specified, then the request is routed to the given `url_prefix` when both request path and request host match at least one entry
 in the corresponding lists.
 
+An optional `src_query_args` can be used for routing requests based on [HTTP query args](https://en.wikipedia.org/wiki/Query_string) additionaly to hostname and path.
+For example, the following config routes requests to `http://app1-backend/` if `db=foo` query arg is present in the request,
+while routing requests with `db=bar` query arg to `http://app2-backend`:
+
+```yaml
+unauthorized_user:
+  url_map:
+  - src_query_args:
+    - name: db
+      value: foo
+    url_prefix: "http://app1-backend/"
+  - src_query_args:
+    - name: db
+      value: bar
+    url_prefix: "http://app2-backend/"

+
+If `src_query_args` contains multiple entries, then it is enough to match only a single entry in order to route the request to the given `url_prefix`.

+If `src_hosts` and/or `src_paths` are specified together with `src_query_args`, then the request is routed to the given `url_prefix` if its host, path and query args

 ### Generic HTTP load balancer
 
 `vmauth` can balance load among multiple HTTP backends in least-loaded round-robin mode.
