Redirecting naked domain to www with DNSimple

由 拜拜、爱过 提交于 2019-12-20 14:16:04
问题 We're using DNS simple to point our domain to our SSL-enabled Heroku app. The behavior we're seeking is as follows: http://ourdomain.com https://ourdomain.com http://www.ourdomain.com Should all permanently redirect to: https://www.ourdomain.com We've already created a CNAME for www.ourdomain.com that points to our app's .herokussl.com domain, but we're not sure what to do with the naked domains. In GoDaddy, we used to do non-masked forwarding. DNSimple doesn't have forwarding, but does have

Extract domain name from a host name

由 不羁的心 提交于 2019-12-20 11:49:39
问题 Is there a programatic way to find the domain name from a given hostname? given -> www.yahoo.co.jp return -> yahoo.co.jp The approach that works but is very slow is: split on "." and remove 1 group from the left, join and query an SOA record using dnspython when a valid SOA record is returned, consider that a domain Is there a cleaner/faster way to do this without using regexps? 回答1: There's no trivial definition of which "domain name" is the parent of any particular "host name".

用bat脚本，测试DNS信息失效时长。 CentOS6.4中named.xx.zone的配置： $TTL=7D 3D ; minimum 测试结果：停止DNS服务，未达到设定的3天的最小期限，DNS信息就失效了。 或者客户端windows2003重启后，DNS信息失效。 1.重启DNS服务 [root@dns3sv named]# service named restart Stopping named: .[ OK ] Starting named: [ OK ] 2.编辑bat脚本，并运行 登录DNS客户端。edit wping2h.bat echo off :while1 date /t & time /t & ping usdb1.te -n 1 | find "usdb1" & @ping 127.0.0.1 -n 7199 -w 1000 > nul goto while1 参数说明： -n 7199个单位，约2小时输出一次结果。 -w 1000毫秒 3.停止DNS服务 [root@dns3sv ~]# date ; service named stop Thu Sep 12 12:37:17 CST 2014 Stopping named: .[ OK ] 4.ping的结果 1天后DNS信息失效，Windows2003 ping不通域名指向的IP。 E:\>echo

Machine's domain name in .NET?

由 江枫思渺然 提交于 2019-12-20 11:08:39
问题 There gotta be an easy way to do this, I can't believe there's none. I have scanned through net and found, like, 20 different methods to find in which domain current user is, but none to get domain (or workgroup) of current machine. In unmanaged c++ this is retrieved by: WKSTA_INFO_100 *buf; NetWkstaGetInfo(NULL, 100, (LPBYTE*)buf); domain_name = pBuf->wki100_langroup; can someone help me, if there's a way to get same info in managed C# natively? EDIT1: Folks, please read the question. I am

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I have a Heroku app and I've add a CNAME (www to herokuapp) to redirect it from GoDaddy to Heroku. Now I'm trying to manage also the naked domain. This is from Heroku documentation. Naked domains (also known as bare domains or apex domains, for example mydomain.com ) must use DNS A-records. To setup your root

Map multiple subdomains to same S3-bucket

由 左心房为你撑大大i 提交于 2019-12-20 09:38:35
问题 Is there some way to map multiple (thousands) of subdomains to one s3-bucket? If so is it also possible to map it to a specific path in the bucket for each subdomain? I want test1.example.com to map to mybucket/test1 and test2.example.com to map to mybucket/test2. I know the last part isn't possible with normal dns-records but maybe there is some nifty Route 53 feature? 回答1: It's not possible with S3 directly. You can only use 1 subdomain with an S3 bucket. However you can map multiple

Programmatically extract keywords from domain names

由 梦想的初衷 提交于 2019-12-20 09:24:33
问题 Let's say I have a list of domain names that I would like to analyze. Unless the domain name is hyphenated, I don't see a particularly easy way to "extract" the keywords used in the domain. Yet I see it done on sites such as DomainTools.com, Estibot.com, etc. For example: ilikecheese.com becomes "i like cheese" sanfranciscohotels.com becomes "san francisco hotels" ... Any suggestions for accomplishing this efficiently and effectively? Edit: I'd like to write this in PHP. 回答1: Ok, I ran the

Varnish: cache only specific domain

由 六眼飞鱼酱① 提交于 2019-12-20 09:02:44
问题 I have been Googling aggressively, but without luck. I'm using Varnish with great results, but I would like to host multiple websites on a single server (Apache), without Varnish caching all of them. Can I specify what websites by URL to cache? Thanks 回答1: (edited after comment) It's req.http.host, so in your vcl file (e.g. default.vcl) do: sub vcl_recv { # dont cache foo.com or bar.com - optional www if (req.http.host ~ "(www\.)?(foo|bar)\.com") { pass; } # cache foobar.com - optional www if
