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

[Ramesh Udari1]

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.

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.

Hi Radu,

Thanks for your response.

Can you please provide sample configuration on RL rewite filter.
