I just wonder can Apache routing be slow?
My situation is this in. I define a ProxyPass, to different the incoming request ( for example, www.example.com ) to the relevant port ( for example, port 81), then at the httpd.conf for the example.com, I will have a few rewrite rules, some of them will direct the request to other domains. The reroutes will at most occurs 3 times. This means that the www.example.com will be reroute to port: 81, and if it matches a certain condition, then it might be rewroute to blog.example.com. And the blog.example.com will then be reroute to port 83 of another pc.
Do you think that such a reroutes will eat up a lot of time?
