Kazakov 0 siblings, 1 reply; 13+ messages in thread From: Per Jakobsen @ 2020-04-19 14:50 UTC (permalink / raw) I'm working on an AWS server that may be deployed to handle multiple Virtual hosts each with different root URIs. For instance a media gallery may be deployed on "http://personal_domain/<user>/gallery" but I may also like to use the same gallery server for "http://company_domain/gallery", both running on the same physical server. Am I right that AWS currently has no predefined dispatchers to handle this situation? Anyone made a "patented" solution for this?

You mean you want to add the domain name to the map's key "gallery" in order to distinguish different contents?

If you query, you'll see that adalog.fr, www.adalog.fr, adenothe.org all refer to the same IP address... I have a real root directory (configured in the server config file), with subdirectories named like the root URL of each virtual host. Here is how I compute the root directory for each virtual host: Hostname : constant String := Status.Host (Request); K : constant Natural := Index (Hostname, ":", Backward); Host_Root : constant String := WWW_Root (Server.Config (Server.Get_Current.all)) & (if K = 0 then Hostname else Hostname (1 ..

K-1)); You are using the HTTP header "Host", right? But if the URI deploys the IP address like: http://192.168.1.1/gallery The host header is meant to serve as an alias, but there is no guarantee it would work, only if the client cooperates. -- Regards, Dmitry A.

Virtual hosts are several logical hosts served by the same physical server. Therefore, by definition, there is no way to distinguish if the user provides just the IP address. But this is a red herring. If you give your visitor a URL that works, and the visitor tries something else and it doesn't work, well... too bad for him. -- J-P.

That was my thought, or if the host header is not given, fall back to one of the other galleries, or even an entirely different one. ~Per ^ permalink raw reply [flat|nested] 13+ messages in thread

That may be tricky, as all images may be fetched on IP-address, but with a session ID I guess that could be solved... ~Per ^ permalink raw reply [flat|nested] 13+ messages in thread

I do something similar on the Ada-Server. Bare IP addresses are treated as a different host (and essentially point to an empty web site). It might break someone's not very well designed tool, but it doesn't matter to any of the major browsers or search bots -- and those are the customers, not the SEO bots and other criminals that may visit. (SEO bots often use IP-only addresses.) Randy. ^ permalink raw reply [flat|nested] 13+ messages in thread
