SID-02389: Cannot get redirect from index.html to work

Status:	Answered	TWiki version:		Perl version:	5.26.1
Category:		Server OS:	Ubuntu 18	Last update:	7 years ago

I cannot get the redirect from / index.html to https://mysite.com/do/view to work.

I have set up a virtual host in apache 2.4 and used the Apache configurator generator to for my site config file.

I've tried the redirect in both .htaccess or the site config file. In either case nothing happens.

I am at complete loss. Below is my site config

Thanx

Gaby

Discussion and Answer

For "Redirect" directive, make sure the "mod_alias" module is enabled.

In your :80, you could redirect directly to your TWiki home, e.g. Redirect permanent / https://dais-wiki.mpi-cbg.de/do/view/Main/WebHome

If a visitor comes in via https, you also need a redirect from :443, e.g. Redirect permanent / https://dais-wiki.mpi-cbg.de/do/view/Main/WebHome

Also, DocumentRoot /srv/vhosts/twiki could be a security issue. The twiki root should not be exposed to the outside; only twiki/bin as script directory using ScriptAlias, and twiki/pub as an html directory using Alias. Set the DocumentRoot do something outside, such as DocumentRoot /srv/vhosts/twiki-html.

Thank you Peter. The redirection on port 80 works fine as you suggested, but the 443 redirection does not work. I get "You don't have permission to access / on this server." I have removed the DocumentRoot directive

-- Gabriella Turek - 2019-02-04

OK, there were a number of problems. I am serving both virtual hosts and regular web pages. Without the DocumentRoot directive it was defaulting to the regular web pages directory hence the error message. So I created the twiki-html directory for just the .htaccess and index.html file. Now everything works.
