     You can avoid `Coordinated Omission Problem` by using `--latency-correction`.
 
+## Dynamic url feature
+
+You can use `--rand-regex-url` option to generate random url for each connection.
+
+```sh
+oha --rand-regex-url http://127.0.0.1/[a-z][a-z][0-9]
+```
+
+Each Urls are generated by [rand_regex](https://github.com/kennytm/rand_regex) crate but regex's dot is disabled since it's not useful for this purpose and it's very incovenient if url's dots are interpreted as regex's dot.
+
+Optionaly you can set `--max-repeat` option to limit max repeat count for each regex. e.g http://127.0.0.1/[a-z]* with `--max-repeat 4` will generate url like http://127.0.0.1/[a-z]{0,4}
+
+If keep-alive is enabled, path and query are generated for each request but shceme, host and port are fixed during connection.
