* Update reverse-proxies.en-us.md

Addition of HAProxy

* Update reverse-proxies.en-us.md

* Apache `ProxyPassReverse` only works for Location, Content-Location and URI headers on HTTP redirect responses, it causes more problems than it resolves. Now all URLs generated by Gitee have the correct prefix AppSubURL. We do not need to set `ProxyPassReverse`.

* fix url param

* use AppSubURL instead of AppURL in api/v1

From Apache: AllowEncodedSlashes not allowed in <Proxy> context

Move this out of <Proxy> block

Fixes #7632

When using wiki page names that include a slash
behind a Apache HTTPD reverse proxy,
AllowEncodedSlashes NoDecode
and appending nocanon to the ProxyPass
directive is required. This commit adds that
information to the documentation.
