HTTP/1.0 Question

Do I need to build for HTTP/1.0 browsers?

[TravelSite]

I am planning to have several domains/websites that actually just point to the one hosting account. I'd use .htaccess to identify the domain that was requested and then load the relevant pages from a database for that particular domain name. This is for part of a small content/website management system that I'm doing (php).

However I read somewhere that this isn't supported in browsers using "HTTP/1.0" standard.

I don't know much about such standards. Would this mean that some users wouldn't be able to see these websites? If so is there a way around this or some alternative implementation? Thanks

..and whether this would effect how search engines view/rank the sites.

HTTP/1.0 did not support the Host: header, which lets the client specify which of several hosts being shared by a single IP address the request is for.

However, long ago, virtually all clients and servers agreed to transmit/receive the Host: header, even when the protocol used is "HTTP/1.0".

Thus, not to worry.

Thanks ronburk,

That's good to know! :)
