Auto-versioning in ASP.NET MVC for CSS / JS Files?

阅读更多关于 Auto-versioning in ASP.NET MVC for CSS / JS Files?

I have read lots of article on how to auto-version your CSS/JS files - but none of these really provide an elegant way to do this in ASP.NET MVC. This link - How to force browser to reload cached CSS/JS files? - provides a solution for Apache - but I'm a little confused how this could be implemented via ASP.NET MVC ? Would anyone be able to provide some advice how to do this on IIS7 and ASP.NET MVC - so that CSS/JS files automatically have a version number inserted in the URL without changing the location of the file ? That is, so links come out link this etc presumably using the URL Rewrite

问题 I have no custom routes in my application, only the default one.

Can I create routes with react-router for a github-pages site?

阅读更多关于 Can I create routes with react-router for a github-pages site?

Ok, so I've made a SPA using React and React-Router and have pushed it to github pages, but none of the routes I have written work when I refresh or click back in my browser. I had the same problem when I was serving the page locally, but then followed along to this SO answer and made a server.js file which provided a redirect to my static HTML page at each route. Here is what the file looks like: "use strict"; let express = require('express'); let path = require('path'); let app = express(); app.use(express.static('public')); app.get('/contact', function(req, res){ res.sendFile('public/index

.htaccess and seo-friendly urls

阅读更多关于 .htaccess and seo-friendly urls

We have an ecommerce site right now that carries a range of brands. The brand pages carry urls as follows: http://www.<DOMAIN>.com/catalog/brand/view?id=2 We need to utilize more friendly (seo-friendly) urls such as: http://www.<DOMAIN>.com/<BRAND> but such that it would resolve #1 above. Is this done in .htaccess files in the root? If so, what is the correct way to go about this? Keep in mind URL#1 is the legitimate address, but we want to utilize the URL#2 format for linking. It's not a 301 type redirect is it? That's more "permanent" unless I misunderstood it or something, no? Many thanks.

Rails routes with optional scope “:locale”

阅读更多关于 Rails routes with optional scope “:locale”

I'm working on a Rails 3.1 app and I'd like to set specific routes for the different languages the app is going to support. /es/countries /de/countries … For the default language ('en'), I don't want the locale to be displayed in the url. /countries Here is the route definition I've set. scope "(:locale)", :locale => /es|de/ do resources :countries end It works great, until I try to use a path helper with 'en' as the locale. In the console : app.countries_path(:locale => 'fr') => "/fr/countries" app.countries_path(:locale => 'en') => "/countries?locale=en" I don't want the "?locale=en". Is
