I want to rewrite a single URL of my website (Joomla) to a friendly URL i.e.
www.example.com/index.php?option=com_mycomponent&view=article&id=10&nav_button=0&article_layout=1&Itemid=503
to
www.example.com/favourit
without disturbing the other URLs of the website
Thank you for your help.
Original question:
Try
RewriteRule ^favourit$ /index.php?option=com_mycomponent&view=article&id=10&nav_button=0&article_layout=1&Itemid=503 [L]
OP springs a sub folder..
If you intend to move the site live, as example.com presumes your already live but your comment suggests your still working on localhost then you should.
Put in the webroot thats / not /mysite
RewriteRule ^mysite/favourit$ /mysite/index.php?option=com_mycomponent&view=article&id=10&nav_button=0&article_layout=1&Itemid=503 [L]
This is temporary so you don't need to fix once you go live.
