I thought I would share this, if anyone ever came across this.
We had a online shop on a http:// domain. and on the same http:// domain we had 3 other sites in sub folder lets call it /site1, /site2 and /site3 so we had:
The online shop – http://www.ourdomain.co.za/
Site 1 – https://www.ourdomain.co.za/site1
Site 2 – https://www.ourdomain.co.za/site2
Site 3 – https://www.ourdomain.co.za/site3
Obviously our shop had categories for example http://www.ourdomain.co.za/category-1
So we decided to move the online shop to a secure site thus changing the http: to https:.
Now in a SEO perspective this is bad because google see’s this as n whole new site and you will loose your ranking, a simple 30 redirect in the index.php on the old root will tell google you have a new site but it still leaves you with a bunch of broken links because http://www.ourdomain.co.za/category-1 will not give you the category anymore it would rather take you to the new home page.. not Ideal.. So how do you redirect ALL old URL’s to the new site and there respective places and still keep Site1, Site2 and Site3 working.. We use .htaccess.
