Symptoms
JIRA is behind IIS and when trying to access JIRA URLs that contain a plus symbol in it, the page doesn't bring JIRA content. Instead, to returns the message "The request filtering module is configured to deny a request that contains a double escape sequence".
The following appears in the screen:
Cause
By default, IIS prohibits any URL that contains a '+' character in the URL from being served.
Resolution
Set IIS to allow double escaping for JIRA site. It can be done in three different ways:
- Directly through IIS console as instructed in this documentation;
Or directly modifying the
web.configfile of the IIS Site, inside the<system.webServer>tag, add the following:<security> <requestFiltering allowDoubleEscaping="true" /> </security>Or via command line in the IIS server:
%windir%\system32\inetsrv\appcmd set config "<JIRA_site_name_in_IIS>" -section:system.webServer/security/requestfiltering -allowDoubleEscaping:true
It may need to restart JIRA site in IIS.
