Can't rewrite path for request from main page when proxy in docker container

Traefik Traefik v1

Hi. I have some problem when send requests to docker container by Traefik 1.7.16 using PathPrefixStrip
example in docker-compose file

service_name:
      container_name: container1
      build: "docker_image/container1"
      labels:
        - traefik.enable=true
        - traefik.backend=container1
        - traefik.frontend.rule=Host:my.site.net;PathPrefixStrip:/web1
        - traefik.docker.network=web
        - traefik.port=8080
      networks:
        - web

When me go to page my.site.net/web1 application return main page with code 200, but all calls from page like /somejs.js looks like my.site.net/somejs.js but not like my.site.net/web1/somejs.js

Can I solve this problem using only Traefik methods or smth?
