I have a magento store but currently decided to add other stores to separate the inventory and also have a clean catalog so i decided to create stores and host them on sub-domains like electronics.mydomain.com and sport.mydomain.com. i followed this tutorial http://www.crucialwebhost.com/blog/how-to-setup-multiple-magento-stores/ but after it the sub-domains were still redirecting to main domain like www.mydomain.com even though i had done nothing with my .htaccess, i found a way to go about it by opening the index.php in my subdomain directory and adding $_GET['___store']= "STORECODE"; and also in my admin panel i typed .mydomain.com in the cookie field and also prolonged the duration to 1 day.
Voila.. everything is working now perfectly until i realized there was a problem, whenever i visit any of my stores(which is installed on the subdomain) and then try to open my main domain that is the www.mydomain.com, it redirects to subdomain.mydomain.com(which is the url of the last subdomain i checked) but then it works again after clearing cookies, i realized the problem is that magento is saving the current store id in the cookie so when i opens my main domain and the cookie is read, that store is returned and therefore the redirect.
Okay , now i have been able to remove the SID from the url and everything works as they share the same cookie domain, now i noticed if i accessed my link like welspot.com?_store=default, the main site opens without a redirect to the subdomain, i was hoping then that anybody could help me redirect all incoming requests under my main domain to mydomain.com?_store=default.
As i still have the problem of cookie redirect, i have hard-coded $_GET['store']="default"; into my index.php file at the head in the main magento installation and now everything works right but there is another problem, when i go to the categories field and i try to select any categories it doesn't select, it just displays create new category instead of selecting and editing the click category and i think it has something to do with adding $_GET['store']="default"; in my index.php because when i remove it everything works but when i remove it and visit my site as welspot.com, based on the recent subdomain i visited it redirects there and i seriously need to solve this problem.
