Description

请问higress可以实现这个需求吗：从请求的url参数里读取key-value并将这个value值作为目的地址进行转发

Why do you need it?

Is your feature request related to a problem? Please describe in details 业务需求，对于长连接业务需要指定到对应的pod。nginx上有类似的配置可以实现：

proxy pass http://$arg_server;

$arg_是nginx原生支持的关键词，可以从url里解析参数(https://nginx.org/en/docs/http/ngx_http_core_module.html#var_arg_) 希望higress也能实现类似功能

Contributor guide

Research direction
Study how Higress handles request routing and variable expansion. Look for existing support for Nginx like variables and implement a feature to extract URL query parameters and use them as dynamic backend addresses.
