Shorten URL using AliasMatch

I'm able to get the following configuration to work:-

Alias /webdoc /data/apps/jenkins/jobs

<Directory /data/apps/jenkins/jobs/[a-zA-Z0-9\-]+/workspace/target/docco>
  Order allow,deny
  Allow from all
</Directory>

With this configuration, I can make the following URL work 

http://myserver/webdoc/HCMS-JS/workspace/target/docco/horizontal/index.html

However, I want to shorten the URL to something like this:-

http://myserver/webdoc/HCMS-JS/horizontal/index.html

I tried the following configuration, but I keep getting 404 when trying to hit the above link:-

AliasMatch ^/webdoc/([a-zA-Z0-9\-]+)/(.*) /data/apps/jenkins/jobs/$1/workspace/target/docco$2

<Directory /data/apps/jenkins/jobs/[a-zA-Z0-9\-]+/workspace/target/docco>
  Order allow,deny
  Allow from all
</Directory>

How do I get this to work? Thanks.

Solution

  • Your AliasMatch lacks a slash:

    AliasMatch ^/webdoc/([a-zA-Z0-9\-]+)/(.*)

    The first match here will be HCMS-JS. The second will be horizontal/index.html. That means that the result will be

    /data/apps/jenkins/jobs/HCMS-JS/workspace/target/doccohorizontal/index.html

    So you need to change the line to be 

    AliasMatch ^/webdoc/([a-zA-Z0-9\-]+)/(.*) /data/apps/jenkins/jobs/$1/workspace/target/docco/$2

    to insert the slash that you didn't capture.

    A good first place to look for these kinds of problems is the apache error log. It should tell you what file it is that it can't find.
