I have a Joomla 3.9.13 site, using Gantry 5.4.31.

I have a limited number of articles I want to remove from my site, and instead of returning a 404 error I want to return a 410 error.

I am not a programmer so I need help in figuring out the correct syntax and location in the .htaccess file to enter the code.

The final name of the articles are like this, and there are 46 of them:

/23-10003-10054-almonds
/90-10310-10027-corn-starch
/25-anticaking-agents
/29-bulking-agents

I would like to know the correct syntax for anything that includes these in them, and it could include additional text before, and additional text after, such as:

/item/23-10003-10054-almonds?88dkdkgdk

or

/item/23-10003-10054-almonds/ldkdjsdhsd

Also, I'd like to know how to tell it which page to deliver. Would it be the default error page? Or should I create some other page? Technically, the content of the visual 410 error page will be the same as my current error page. But I'm not sure how Joomla with Gantry constructs the error page. If it's easier, I'll just create a page to use. Either way, what is the syntax for the .htaccess page to tell it where to find the correct error page?

Below is my current .htaccess file, with some items removed I know aren't relevant:

##
# @package    Joomla
## No directory listings

<IfModule autoindex>
  IndexIgnore *
</IfModule>

## Can be commented out if causes errors, see notes above.
Options +FollowSymlinks
Options -Indexes

## Mod_rewrite in use.

    /23-10003-10054-almonds - do the format of the URLs you want to remove differ from the other URLs? Or is there no discernible difference? eg. The URLs you've listed all start with 2 digits in the path segment. Are these 2 digits common for all URLs or unique to the ones you want to remove? – MrWhite Dec 19 '19 at 10:15

    No, all my articles have numbers at the start. There's no real pattern that makes them unique. – Thora Dec 20 '19 at 15:36

You could create 46 rewrite rules like this. They would need to go into your .htaccess file before the ## Begin - Joomla! core SEF Section.

RewriteRule ^/?23-10003-10054-almonds - [G,L]
RewriteRule ^/?90-10310-10027-corn-starch - [G,L]
RewriteRule ^/?25-anticaking-agents - [G,L]
RewriteRule ^/?29-bulking-agents - [G,L]
  • ^ means that "starts with"
  • /? is an optional starting slash. This could be omitted in .htaccess. The starting slash needs to be on the rule in Apache .conf files and needs to be omitted in .htaccess. Making it optional with the question mark makes the rule more portable and able to be used in either place.
  • - means to leave the URL alone and not change it
  • G means "Gone" -- send the 410 status
  • L means "Last" -- so that no other rewrite rules are executed

These rules are going to execute for each and every request to your webserver. Having 46 of them is probably fine. If you were to expand to hundreds or rules, it could hurt performance.

You could also try combining them into one rule which might perform a bit better: RewriteRule ^/?((23-10003-10054-almonds)|(90-10310-10027-corn-starch)|(25-anticaking-agents)|(29-bulking-agents)) - [G,L] However, the rule would be very long and might be hard to maintain.

It doesn't look like Joomla supports sending a 410 status for removed articles out of the box. The Joomla Stack Exchange site has a couple questions about 410 codes:

However, neither of those exactly matches your situation. It might be worth asking there if there is a way to have Joomla return the 410 error rather than trying to do it in .htaccess.
