I’ve create a wpmu with the command sudo ee site create wpsubdir w3tc
which is behind a reverse proxy. and let the reverse proxy rewrite b.85xt.cn to
now,I can access my wp in the Internet,by domain b.85xt.cn.
still there is some place show ,because these place use a relatvie path,no at all.
for example,link ‘my site’,‘new’,etc.

I am sorry but I failed to understand your problem.
