问题 What characters are you allowed to use in a subdomain? Example: for someSub.example.com the someSub portion. I know you can use letters, numbers, and hyphens, but what about other characters? Can _ (underscore) be used? 回答1: Letters (except stressed à), Numbers 0-9 and Hyphen. http://en.wikipedia.org/wiki/Domain_name excerpt: Valid characters that can be used in a domain name are: a-z 0-9 - but not as a starting or ending character . as a separator for the textual portions of a domain name

Asp.net mvc 301 redirect from www.domain.com to domain.com

由 牧云@^-^@ 提交于 2019-11-26 16:31:49
问题 We have a website at domain.com, which is also accessible via a CNAME entry for www.domain.com that points back to domain.com. We'd like all visitors to www.domain.com to be redirected to domain.com using a 301 redirect. What's the best way to implement this in asp.net mvc? In global.asax? 回答1: I accept that doing this at application level is non-desirable as per the comments to the question. Installing the HTTP Redirect feature in IIS7 is the best way to do this. In our case, other

I am used to working on httpd ( Apache ) which provides a way to configure subdomains which is mapped to a directory. How can I do the same thing in Connect.js/Express.js ? I see that the only thing that I have is routes which I am not sure how I can use to configure sub domains. I have subdomains like m.mysite.com, sync.mysite.com Can someone help ?

Then, create several sites in their own directory and export the express app, eg. /path/to/m/index.js : var app = express() /* whatever configuration code */ exports.app = app // There is no need for

Amazon S3: Static Web Sites: Custom Domain or Subdomain

由 我的未来我决定 提交于 2019-11-26 15:06:19
问题 Amazon.com just announced that one can host static web sites in a S3 bucket. I went to their setup page at http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?WebsiteHosting.html and created a bucket for my static web site, and it worked fine.

However, I would like to point a subdomain that I own (e.g. static.mydomain.com) to my static web site at Amazon S3. Has anybody figured out how to do

How do I get a list of all subdomains of a domain? [closed]

由 自闭症网瘾萝莉.ら 提交于 2019-11-26 14:58:35
问题 I want to find out all the subdomains of a given domain. I found a hint which tells me to dig the authoritative Nameserver with the following option: dig @ns1.foo.bar some_domain.com axfr But this never works. Has anyone a better idea/approach 回答1: The hint (using axfr) only works if the NS you're querying (ns1.foo.bar in your example) is configured to allow AXFR requests from the IP you're using; this is unlikely, unless your IP is configured as a secondary for the domain in question.

PHP Getting Domain Name From Subdomain

由 混江龙づ霸主 提交于 2019-11-26 14:37:33
I need to write a function to parse variables which contain domain names. It's best I explain this with an example, the variable could contain any of these things: here.example.com example.com example.org here.example.org But when passed through my function all of these must return either example.com or example.co.uk, the root domain name basically. I'm sure I've done this before but I've been searching Google for about 20 minutes and can't find anything. Any help would be appreciated. EDIT: Ignore the .co.uk, presume that all domains going through this function have a 3 letter TLD. Sampson

Can HTML5 databases and localStorage be shared across subdomains?

由 一笑奈何 提交于 2019-11-26 14:31:26
I am attempting to share data across subdomains using Safari. I would like to use an HTML5 database (specifically localStorage as my data is nothing but key-value pairs). However, it seems as though data stored to domain.com can not be accessed from sub.domain.com (or vice versa). Is there any way to share a single database in this situation? super1ha1 Update 2016 This library from Zendesk worked for me. Sample: Hub // Config s.t. subdomains can get, but only the root domain can set and del CrossStorageHub.init([ {origin: /\.example.com$/, allow: ['get']}, {origin: /:\/\/(www\.)?example.com$/,

After that, you can use the following rule to rewrite
