The Global Redirect Module checks urls as they are created, adjusts duplicates and creates an automatic redirect when a URL changes. This prevents broken links when changes to the page names result in a new URL.
Specifically, the Global Redirect Module:
- Checks the current page URL for an alias and does a 301 redirect to it if it is not being used.
- Checks the current page URL for a trailing slash, removes it if present and repeats check 1 with the new request.
- Checks if the current page URL is the same as the site_frontpage and redirects to the frontpage if there is a match.
This module is enabled as part of YaleSites Core and should never be disabled.
Infinite loop error message
The Global Redirect Module is a convenient tool for redirecting old site URLs to a newly created URL. However, there is a bug that creates some confusion because the redirects happen automatically without any configuration.
The error message that displays is:
“Oops, looks like this request tried to create an infinite loop. We do not allow such things here. We are a professional website!”
This happens when the page is saved 2 or more times and the final save changes the URL to one that has already been used for the page. So:
- yalesites.yale.edu/contact was changed to
- yalesites.yale.edu/contact-us, then changed back to
- yalesites.yale.edu/contact
Since the first and third URLs are the same, it basically creates a redirect that points to a URL that already exists.
Solution: just delete all the redirects except for the last one created.
- Click on the Edit tab and scroll down to the Vertical Tabs.
- Click on the URL Redirects tab.
- Delete the extra redirects.
