OK, I have 10 subdomains attached to 1459919.com which goes like this: 0.1459919.com 1.1459919.com ... 9.1459919.com. Before I moved the sites from cpanel hosting to my own server running ISPconfig, I created using cPanel's Subdomains' function, which automated everything, including creating the needed subfolders on 1459919.com and proper pointing to them. Anyway, a few days ago I moved this site 1459919.com to my own server running ISPconfig, and I wanted to reproduce what cPanel did without creating all 10 subdomain sites with ISPconfig's "Add new website" function but simply with its "Subdomain for website" function. To some extent, I have achieved what I wanted so to speak, but with some regret. Take this subdomain http://1.1459919.com for example, most browsers will redirect it to the secure URL: https://1.1459919.com which I wanted. However, if I add some non-existing words at the end of the subdomain, I would normally expect to get a 404 error and then redirect that to my 404.php (to explain I did not migration everything over to the new server). Instead of getting a 404 error, the browsers simply stay at whatever I entered, for example, 1.1459919.com/non-existing, 1.1459919.com/non-existing.html, etc. For the trunk website 1459919.com I use this setup: For the subdomain setup, it is like this for 1.1459919.com according to what I searched and found on this forum... So, is "L" the correct tag? Should I use R, No tag, or whatever for this purpose? The reason, I did not use the "Add new website" to create any of these subdomains as stand alone website is because I do not want to end up of having 10 websites/FTPs to manage.
