forward

The controller redirect() method in Lithium does an actual HTTP redirect. But is there a method to simply forward a request to another controller/action without an HTTP redirect? For example, say I want to add an authentication layer and rather than redirecting the user to a "/auth/login" page, the login layout and template get rendered rather than the content for the page they requested. Then, when they submit the form and they authenticate, they're already on the page they requested. Zend framework has something similar with a _forward() method. Thanks! There's no method, mostly because you

my issue is identical to the thread below, I'm struggling to understand the answers given, or rather my code shouldn't work as it only uses input iterators ..but my func appears to work and behave identically to std::search ..so I'm at a loss and loathe to move on without understanding properly ...maybe if someone can suggest an input that will break my function but not the std:: From Why do I need a Forward Iterator to implement my customized std::search : I am studying the book "Accelerated C++" from Koenig & Moo. Exercise 8-2 ask me to implement on my own some templatized functions from

For example, if I have set an animation on an element to take 10 seconds, can I jump to '5 seconds' into that animation? Preferably, this could be set with a percentage. 回答1: http://api.jquery.com/queue/ you could try to set up a queue in your animation OR if you could provide an example surely you could receive a good hint ;) 回答2: You can stop the current animation, set the state of the animated object to halfway between its initial state and final state and then start a

If you take the cases where you need to iterate over some data, and can do in a read only manner, are fast forward (read only forward) cursor more or less inefficient than say while loops? From my investigations it looks as though the cursor option is generally faster and uses less reads and cpu time. I haven't done any extensive testing, but is this what others find? Do cursors of this type (fast

1.从地址栏显示来说 forward是服务器请求资源,服务器直接访问目标地址的URL,把那个URL的响应内容读取过来,然后把这些内容 再发给浏览器.浏览器根本不知道服务器发送的内容从哪里来的,所以它的地址栏还是原来的地址. redirect是服务端根据逻辑,发送一个状态码,告诉浏览器重新去请求那个地址.所以地址栏显示的是新的URL.所 以redirect等于客户端向服务器端发出两次request，同时也接受两次response。 谁能解释一下这两段话的意思，尤其是后一段的2次？？？？ 回答列表: forward：A访问B，B访问C,过程是A-->B-->C，此时打开的是C，但地址栏里的地址是B的地址。 redirect:A访问B，若想访问C，需由B返回给A一个参数，由A去访问C，过程是A-->B-->A-->C,地址栏的地址是C。2次的意思是指一次访问B，一次访问C redirect先要返回上一请求，然后在访问下一请求。 通俗的说： 当一个客户端访问服务器端的一个JSP（本质上就是一个SERVLET），当调用response.sendRedirect，实际上它做的是从服务器端往客户端发一个指令，告诉IE把地址拦自动变成第2个页面，并点一下转到那个按钮，客户端接到这个指令后马上去访问第2个JSP，第2个JSP再把算出的结果返回客户端。。。。。。 forward

I searched the internet and stackoverflow but all of the questions regarding forward declarations of enumerators refer to c++. What do you do for declaring enumerators in C? Put them at the top of each file (or in an include) so that all functions in the file can access them? Thanks 回答1: Put them in a header so that all files that need them can access the header and use the declarations from it. When compiled with the options: $ /usr/bin/gcc -g -std=c99 -Wall -Wextra -c enum.c $ GCC 4.2
