domain-name

I am wondering what the best way to obtain the current domain is in ASP.NET? For instance: http://www.domainname.com/subdir/ should yield http://www.domainname.com http://www.sub.domainname.com/subdir/ should yield http://sub.domainname.com As a guide, I should be able to add a url like "/Folder/Content/filename.html" (say as generated by Url.RouteUrl() in ASP.NET MVC) straight onto the URL and it should work. Same answer as MattMitchell's but with some modification. This checks for the default port instead. Edit: Updated syntax and using Request.Url.Authority as suggested $"{Request.Url

I'm building a website using Django. The website could have a significant number of users from non-English speaking countries. I just want to know if there are any technical restrictions on what types of characters an email address could contain. Are email addresses only allowed to contain English letters, numbers, _ , @ and . ? Are they allowed to contain non-English alphabets like é or ü ? Are they allowed to contain Chinese or Japanese or other Unicode characters? Email address consists of two parts local before @ and domain that goes after. Rules to these parts are different: For local

I have a URL which can be any of the following formats: http://example.com https://example.com http://example.com/foo http://example.com/foo/bar www.example.com example.com foo.example.com www.foo.example.com foo.bar.example.com http://foo.bar.example.com/foo/bar example.net/foo/bar Essentially, I need to be able to match any normal URL. How can I extract example.com (or .net, whatever the tld happens to be. I need this to work with any TLD.) from all of these via a single regex? Well you can use parse_url to get the host: $info = parse_url($url); $host = $info['host']; Then, you can do some

I have 3 domain names and am trying to host all 3 sites on one server (a Digital Ocean droplet) using Nginx. mysite1.name mysite2.name mysite3.name Only 1 of them works. The other two result in 403 errors (in the same way). In my nginx error log, I see: [error] 13108#0: *1 directory index of "/usr/share/nginx/mysite2.name/live/" is forbidden . My sites-enabled config is: server { server_name www.mysite2.name; return 301 $scheme://mysite2.name$request_uri; } server { server_name mysite2.name; root /usr/share/nginx/mysite2.name/live/; index index.html index.htm index.php; location / { try_files

Is it possible without using regular expression? For example, I want to check that a string is a valid domain: domain-name abcd example Are valid domains. These are invalid of course: domaia@name ab$%cd And so on. So basically it should start with an alphanumeric character, then there may be more alnum characters plus also a hyphen. And it must end with an alnum character, too. If it's not possible, could you suggest me a regexp pattern to do this? EDIT: Why doesn't this work? Am I using preg_match incorrectly? $domain = '@djkal'; $regexp = '/^[a-zA-Z0-9][a-zA-Z0-9\-\_]+[a-zA-Z0-9]$/'; if
