I don't seem to be able to get a functional /do scriptalias working that will also load content which is in <home>/twiki/pub

here are my aliases including one I added to no avail.

Alias /do/TWiki/ "/opt/was/archwiki/twiki/pub/TWiki"
ScriptAlias /do "/opt/was/archwiki/twiki/bin"
Alias /pub "/opt/was/archwiki/twiki/pub"

here are errors from access and error logs

I used the apache twiki.conf generator to get this far....

Any suggestions please? my /do/configure html is attached

Discussion and Answer

Don't mix TWiki's bin and pub in your Apache configuration. Use /do URL path for the TWiki bin, and /pub URL path for the TWiki pub.

-- Peter Thoeny - 2014-02-14

I'm using the distribution libraries they way they were expanded from the .tar file.

the log files below were generated with:

ScriptAlias /do "/opt/was/archwiki/twiki/bin"

# The Alias defines a url that points to the twiki pub directory, which
# is the root of file attachment
Alias /pub "/opt/was/archwiki/twiki/pub"

So I believe the /do is causeing the /view to be included in what should be the /pub call

I'm not sure what the perl script view is doing but it appears not to work

So .... what should my ScriptAlias and Alias be? and/or what else do I need to do?

Use ApacheConfigGenerator

-- Peter Thoeny - 2014-02-15

Actually the problem was in the configurator. The name of the alias for the script directory was /do which is right BUT, the name of the alias for the pub directory was also /do . So....we saw the misdirected static content which was trying to be loaded from <twiki> /bin/view

-- Richard Floyd - 2014-02-18

I just checked, the ApacheConfigGenerator shows /pub for pub alias as it should be.

-- Peter Thoeny - 2014-02-20

twiki view page images are not displayed. I have generated my apache config file using ApacheConfigGenerator.

-- Sachin Vaidya - 2015-08-20

If images are not shown it means that the twiki/pub directory is not exposed as a document root directory by Apache.

In the twiki.conf Apache config file for TWiki make sure the alias is set properly, such as:

Alias /pub "/var/www/twiki/pub"

...and that the <Directory "/var/www/twiki/pub"> directive has the proper settings as per ApacheConfigGenerator.

Make sure PubUrlPath and PubDir are set properly in TWiki's configure, such as:

$TWiki::cfg{PubUrlPath} = '/p/pub';
$TWiki::cfg{PubDir} = '/var/www/twiki/pub';

Also, please do not cross-post questions.
