Hello Virtuemart community!
Joomla 3.9.12.
VirtueMart 3.6.2 10159
PHP Version 7.2.22
Browsing my access logs I noticed that component/ajax/?format=json call where systematically followed by a /component/ajax?format=json
Looking in the source code I found this line
system.keepalive":{"interval":300000,"uri":"\/component\/ajax\/?format=json"}
in <script type="application/json" class="joomla-script-options new">
I guess it should be written: system.keepalive":{"interval":300000,"uri":"\/component\/ajax?format=json"} to avoid the redirect.
[EDIT: At the moment, I searched for the string but I only find it in the cached pages. Any idea where I can find the string to edit?
And I realize this is a Joomla issue, not a virtuemart issue, still if anyone can help
