Question

hi,

just installed 4.0.4-2 and is trying to get twiki to authenticate my /twiki/pub/ directory this works fine for non-hierical webbs but for hierical webbs I have problems (followed TWikiAccessControl -> Controlling access to Attachments).

Here are some some snippets from the rewrite.log (running apache 1.3).

• Using non-hierical webbs (OK):

I try to get "/twiki/pub/One/WebHome/data.zip" this gets rewritten by apache to "/twiki/bin/viewfile/One/WebHome?filename=data.zip"

Download is successful.

• Using hierical webbs (problem):

I try to get "/twiki/pub/One/Two/WebHome/data.zip" this gets rewritten by apache to "/twiki/bin/viewfile/One/WebHome?filename=data.zip" for some reason the "Two"-webb is lost when sent to viewfile thus viewfile cant find file.

Is it my apache or is it the regexp that causes the problems?

Summary

Regexp (from doc mentioned above):

RewriteRule ^/+twiki/+pub/+([^/]+)/+((([^/]+)/+)+)(.+) /twiki/bin/viewfile/$1/$4?filename=$5 [L,PT]

To be rewritten: /twiki/pub/One/Two/WebHome/data.zip

Received: /twiki/bin/viewfile/One/WebHome?filename=data.zip

Expected: /twiki/bin/viewfile/One/Two/WebHome?filename=data.zip

Answer

fyi I got it working when I changed to:

RewriteRule ^/+twiki/+pub/+(.+)/*/(.+) /twiki/bin/viewfile/$1?filename=$2 [L,PT]

In apache config, but I'd really would like to know if this is a problem in my installation, twiki or apache.

It's just a problem to determine, which part of the uri is the web, which one the topic and which one the filename.

I would use something like this:

RewriteRule ^/+twiki/+pub/+([^/]+(/+[^/]+)*)/+([^/]+)/+(.+) /twiki/bin/viewfile/$1/$3?filename=$4 [L,PT]

Holger, this assumes a flat web structure. The regex needs to be changed if you have sub webs.

Hi,

Have a look at SecuringAttachments , The approach is different from mod_rewrite stuff- Look at my comments at the end of the topic. I have also attached perl module which helps to check the ACL of topic(hence attachments).

See also ViewFileNotWorkingWithNestedWebs. The new regex I came up with is:

RewriteRule ^/+twiki/+pub((/+[^/]+)+)/+(.+) /twiki/bin/viewfile$1?filename=$3 [L,PT]
