AEM adds ‘.html’ to the Redirect URL of Internal Pages

Description

Environment
Experience Manager

Issue/Symptoms
AEM adds .html to the URL fragment (or anchor, the last part of the URL starting from #). For example:

/content/we-retail/us/en/men.html#FEATURED - /content/we-retail/us/en/men.html#FEATURED.html

Steps to reproduce:

1-Create a new content page page1 under /content/we-retail.

2-Select page1  Properties.

3-In Advanced tab  'Redirect' field, set '/content/we-retail/us/en/men.html#FEATURED'.

4-Access page1 with 'View as Published'.

$  curl -v -u admin:admin http://localhost:6402/content/we-retail/page1.html?wcmmode=disabled

* About to connect() to localhost port 6402 (#0)

...

HTTP/1.1 302 Found

X-Content-Type-Options: nosniff

Content-Type: text/html;charset=utf-8

Location: http://localhost:6402/content/we-retail/us/en/men.html#FEATURED.html?wcmmode=disabled

Content-Length: 0

* Connection #0 to host localhost left intact

Resolution

This is a hard-coded behavior. The com.day.cq.wcm.foundation.impl.PageRedirectServlet#doGet is adding .html to the redirect URL if the redirect target is a space within the same AEM.
