Symfony2.2 render ESI template

阅读更多关于 Symfony2.2 render ESI template

问题 From the documentation, there is no example of how to render a template inside template using ESI. Is it possible to do that? For example, I have a template index.html.php and I want to render form.html.php template with ESI. How to do that? 回答1: As the documentation page you provided, you can render one controller within another using: {{ render_esi(controller('YourBundle:Default:news', { 'max': 5 })) }} You can also use a route name instead of the controller reference: {{ render_esi(url(

问题 In our Symfony2 Application we render reusable blocks with render_esi. We have this kind of templates: {% for products as product %} <div class="product"> <h4>{{ product.name }}</h4> <div class="ratings"> {{ render_esi(controller('AcmeDemoCommunityBundle:Rating:ratingStars', { objectType: 'product', objectId: product.id, readOnly: true })) }} </div> </div> {% endfor %} And of cause we use the render_esi also in the detail page of the product. 回答1: I would like to differentiate different types

问题 I'm trying to setup Varnish to process ESI includes on a local environment. I am running varnish in a virtual machine and the content is running on the host machine. I have two files "index.html" and "test.html". These are both stored in a folder called "esi" in the docroot of an apache server. index.html <h1>It Works!</h1> <esi:include src="test.html" /> test.html <p>ESI HAS BEEN INCLUDED</p> Varnish is running on the virtual machine on port 8000. So I access it here: http://192.168.56.101

Security ESI issue with symfony2

阅读更多关于 Security ESI issue with symfony2

问题 I'm facing a security problem with ESI on Symfony2 (2.2) : Some ESI of my application don't require to be logged and are public, but other ESI required the user to be logged and have the role ROLE_USER, for example. The problem is that every guy can display an ESI, by writing its URL in the address bar of the navigator... So a man can access to a ESI (that is called inside an action which requires an admin role), even none logged ! For example, my ESI "SybioWebsiteBundle:Controller

With Symfony2 why are ESI tags inside cached responses ignored?

阅读更多关于 With Symfony2 why are ESI tags inside cached responses ignored?

问题 I have an ecommerce application that I'm try to set up for caching - initially via the Symfony2 Reverse Proxy, but then ultimately via Varnish in production. I'm using Symfony 2.1.8 on Apache2. My problem is I cannot get the ESI tags to be re-checked for each request when the primary controller action is cached (important for private content like the basket contents), but I don't understand why. For example, I cache the homepage with the following code: public function indexAction(Request
