forward

I think a common problem is trying to forward (post) data to another page. Normally, I'd resort to sessions to pass data between pages, but this forward helper in Zend looks like it has potential. Is there any way to get information about a forward request? Like ask for the forwarder (and it'd return null normally when there's no forwarder)? And if there's no current implementation, is it possible? It'd be a fun project, and something I've wanted forever anyways. (I'm also currently using my own BcryptDbTableAuth class until I find a better solution). By the way, I'm not talking about adding

I want to predict certain values that are weekly predictable (low SNR). I need to predict the whole time series of a year formed by the weeks of the year (52 values - Figure 1) My first idea was to develop a many-to-many LSTM model (Figure 2) using Keras over TensorFlow. I'm training the model with a 52 input layer (the given time series of previous year) and 52 predicted output layer (the time series of next year). The shape of train_X is (X_examples, 52, 1), in other words, X_examples to train, 52 timesteps of 1 feature each. I understand that Keras will consider the 52 inputs as a time

I always read that std::forward is only for use with template parameters. However, I was asking myself why. See the following example: void ImageView::setImage(const Image& image){ _image = image; } void ImageView::setImage(Image&& image){ _image = std::move(image); } Those are two functions which basically do the same; one takes an l-value reference, the other an r-value reference. Now, I thought since std::forward is supposed to return an l-value reference if the argument is an l-value reference and an r-value reference if the argument is one, this code could be simplified to something like

一、 netfilter和iptables说明： 1、 netfilter/iptables IP 信息包过滤系统是一种功能强大的工具，可用于添加、编辑和除去规则，这些规则是在做信息包过滤决定时，防火墙所遵循和组成的规则。这些规则存储在专用的信息包过滤表中，而这些表集成在 Linux 内核中。在信息包过滤表中，规则被分组放在我们所谓的链（chain）中。 虽然 netfilter/iptables IP 信息包过滤系统被称为单个实体，但它实际上由两个组件 netfilter 和 iptables 组成。 (1). netfilter 组件也称为 内核空间（kernelspace） ，是内核的一部分，由一些信息包过滤表组成，这些表包含内核用来控制信息包过滤处理的规则集。 (2). iptables 组件是一种工具，也称为 用户空间（userspace） ，它使插入、修改和除去信息包过滤表中的规则变得容易。 iptables包含4个表，5个链。其中表是按照对数据包的操作区分的，链是按照不同的Hook点来区分的，表和链实际上是netfilter的两个维度。 2、 4个表:filter,nat,mangle,raw，默认表是filter（没有指定表的时候就是filter表）。表的处理优先级：raw>mangle>nat>filter。 filter ：一般的过滤功能 nat:

iptables只是 linux 防火墙的管理工具而已，位于/sbin/iptables。真正实现防火墙功能的是netfilter，它是linux内核中实现包过滤的内部结构。 iptables包含4个表，5个链。其中表是按照对数据包的操作区分的，链是按照不同的Hook点来区分的，表和链实际上是netfilter的两个维度。 4个表:filter,nat,mangle,raw，默认表是filter（没有指定表的时候就是filter表）。表的处理优先级：raw>mangle>nat>filter。 filter：一般的过滤功能 nat:用于nat功能（端口映射，地址映射等） mangle:用于对特定数据包的修改 raw:有限级最高，设置raw时一般是为了不再让iptables做数据包的链接跟踪处理，提高性能 5个链：PREROUTING,INPUT,FORWARD,OUTPUT,POSTROUTING。 PREROUTING:数据包进入路由表之前 INPUT:通过路由表后目的地为本机 FORWARDING:通过路由表后，目的地不为本机 OUTPUT:由本机产生，向外转发 POSTROUTIONG:发送到网卡接口之前。 规则表： 1.filter表——三个链：INPUT、FORWARD、OUTPUT 作用：过滤数据包 内核模块：iptables_filter. 2.Nat表——三个链

iptables -F # -F 是清除的意思，作用就是把 FILTRE TABLE 的所有链的规则都清空 iptables -A INPUT -s 172.20.20.1/32 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT # 在 FILTER 表的 INPUT 链匹配源地址是 172.20.20.1 的主机，状态分别是 NEW,ESTABLISHED,RELATED 的都放行。 iptables -A INPUT -s 172.20.20.1/32 -m state --state NEW,ESTABLISHED -p tcp -m multiport --dport 123,110 -j ACCEPT # -p 指定协议， -m 指定模块 ,multiport 模块的作用就是可以连续匹配多各不相邻的端口号。完整的意思就是源地址是 172.20.20.1 的主机，状态分别是 NEW, ESTABLISHED,RELATED 的， TCP 协议，目的端口分别为 123 和 110 的数据包都可以通过。 iptables -A INPUT -s 172.20.22.0/24 -m state --state NEW,ESTABLISHED -p tcp -m multiport --dport 123,110 -j

I want to alert() when browser's back or forward button is clicked or hash is changed in javascript. I have tried this solution and it is working but it is causing problems on other links in webpage and submit each request twice on any link click event. Is there any solution to capture it without using setInterval() function? So I need to capture hash change or back/forward button click event? I need a simple javascript code/function/property that should work in all modern browsers. Any solution ? Thanks Robert Koritnik Not a good idea Can you rather explain the reasoning behind this? We've
