How to redirect to maintenance page when JIRA Tomcat server is down.

Question

Hi, We want to redirect users to maintenance page, when ever we do releases our jira over production instance. Here make a note that user should not access jira, but jira administrator/Dev team should access jira at that time. Is there any configuration in tomcat server to achieve this.

Hi Radu,

Thanks for your response.

Can you please provide sample configuration on RL rewite filter.

I do not know what you mean by "down". From your words, JIRA (tomcat) is not really down.

Anyway, if If I remember well, this is achievable in Apache using mod_rewrite: http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html

RewriteEngine on
RewriteCond   %{REQUEST_URI} !-U
RewriteRule   ^(.+)          error_page.html

Take care that it will mean a perf penalty, since the condition is always checked.

Since JIRA includes a URL rewite filter (org.tuckey.web.filters.urlrewrite.UrlRewriteFilter) you can check the 
documentation and develop a condition on it so that you will redirect the normal users to an error page, I guess, 
and that would better suit your request.
