We have a problem whit one of our TYPO3 installations. The Bingbot which visits the site calls a controller of the old ext_form extension without parameters and creates an error.
207.46.13.XXX - - [16/Oct/2018:00:18:48 +0200] "GET example.html?tx_form_form%5Baction%5D=process HTTP/1.1" 200 10256 "-" "Mozilla/5.0 (compatible; bingbot/2.0; +http://www.bing.com/bingbot.htm)"
The problem for us is not that this happens but that TYPO3 is caching the site with "Oops, an error occurred! Code: 20181016001848e0153dcf" as content.
Is there a way to say TYPO3 to not cache the site if an error occorres or to send the bot to the 404 site if he calls the site with false parameters.
There are several things you can do:
robots.txt
(Edit: After consideration this solution is probably unsuitable for the specific problem).htaccess
if the page is called without required parameter, a redirect should be recognized by the bot too.EDIT:
Example for htaccess (not tested):
RewriteCond %{QUERY_STRING} .+
RewriteRule ^example.html?tx_form_form%5Baction%5D=process$ example.html [L,R=301,QSD]
The target example.html
can be anything, either a custom 404 page or just the list-view. The code 301
in [L,R=301,QSD]
can be adjusted according to HTTP Status Codes (3xx). If it's redirected to a (custom) 4xx page the HTTP status code should be accordingly (404
, or perhaps another 4xx-status-message i.e. 400
).
