Question

When trying to access my TWIKI intranet site from outside our network, the links or wikiwords won't load. When you click them, they specifiy a local URL instead of the public URL.

eg. http://servername.domain.local/... instead of the required http://publicurl.companyname.com/...

The HTTP_Host value is set to servername.domain.local but I can't figure out how to change that or override it.

I am very new to TWIKI so I know very little about scripting and the like.

Does anyone know how I can fix this?

The contents of the %HTTP_HOST% variable doesn't come from TWiki, it is configured in the web server's configuration (Configuration item ServerName). You might also want to check Apache's UseCanonicalName setting: You need to set this to 'Off' if you want the server to keep the name supplied by the client.

Harald, Thanks for the quick reply. I've double checked the settings for ServerName and UseCanonicalName and both are set correctly. However, the TWIKI configuration still displays the server.domain.local value for HTTP_HOST. And the links continue to error.

Any place else I can look?

The configure has a {DefaultUrlHost} to specify the host name. However, this is only used if TWiki cannot figure out the host name, such as when running a script from the shell instead of cgi. When you access the view script as a cgi it is picking up the host name dynamically from the current URL, and uses that for the internal links. That is, links are supposed to working properly, even if you can access your data with two different URLs (host names). I am not sure why this does not work in your case.

Peter, Thanks for the information. I loaded configure and in the General Path Settings section I have a {wikiHomeUrl} but no {DefaultURLHost} variable listed. The {wikiHomeURL} is set to the correct URL.

Unfortunately I am so new to this I don't know if we are accessing this through a CGI script or not. How would I tell?

As stated, it should "just work".

You need to work with your local sysadm on the apache installation to get this worked out; it is the apache setup that is the problem here.

The fix to this problem was with our firewall. We are using MS ISA 2000 for our firewall. When I set up the web publishing rules I failed to notice a check box that will send the original host header instead of substituting the header created by the firewall. I'm still learning.
