参见图2所示的工作流程示意图，在第一实施例中，本申请公开一种网络攻击判断方法，该方法应用于浏览器客户端，所述网络攻击判断方法包括：
步骤S11、获取网络根据网页浏览请求返回的反馈信息。
如果浏览器客户端在请求网页数据的过程中受到了网络攻击，网络返回的反馈数据可能被篡改，则在获取网络返回的反馈信息后，可以通过对反馈信息做出进一步的数据处理，来判断浏览器客户端在请求网页数据的过程中是否受到了网络攻击。网络攻击可能发生于网络中的不同节点，则 所述反馈信息可以，但不限于为域名解析信息和网络根据所述网页浏览请求返回的响应信息。
所述域名解析信息可以从域名解析服务器返回。例如，若需要浏览网页，浏览器客户端会根据用户网页浏览请求的操作产生网页浏览请求，在将所述网页浏览请求传输至网页服务器之前，需要获取域名解析服务器对所述网页浏览请求的域名解析信息。所述响应信息可以由目标服务器返回，例如，若需要浏览网页，浏览器客户端会产生网页浏览请求，并将所述网页浏览请求传输至目标服务器，在传输过程中，网络会返回所述网页浏览请求对应的响应信息。
步骤S12、将获取到的攻击规则与所述反馈信息进行匹配对比，根据对比结果确定所述网页浏览请求是否受到网络攻击，其中，所述攻击规则是由规则配置服务器发送的。
本申请中，通过规则配置服务器制定各条攻击规则，并由所述规则配置服务器将各条攻击规则传输至浏览器客户端。
在获取到所述反馈信息后，可以通过检验反馈信息是否被篡改或者出现数据错误来判断浏览器客户端在请求网页数据的过程中是否收到网络攻击。例如，域名解析服务器在解析网页浏览请求的过程中，有可能受到网络攻击，导致域名解析出现错误；或者，在将所述域名解析信息传输至浏览器客户端的过程中，受到网络攻击，导致域名解析信息中的IP地址被篡改。这都会导致所述域名解析信息中包含的IP地址为错误的IP地址，从而导致浏览器客户端无法获取到正确的IP地址，从而无法获取所需的网页数据。再例如，在浏览器发出网页浏览请求后，网络中的节点将本次网页浏 览请求重定向至非法的目的地址，或者修改网络浏览请求对应的渠道号等。
本申请公开的网络攻击判断方法，应用于浏览器客户端，在该方法中，所述浏览器客户端在获取网络根据网页浏览请求返回的反馈信息后，将攻击规则与所述反馈信息进行匹配对比，根据对比结果判断所述网页浏览请求是否受到网络攻击，从而能够识别是否受到网络攻击。
进一步的，当通过检验域名解析信息来判断是否收到网络攻击时，所述将获取到的攻击规则与所述反馈信息进行匹配对比，根据对比结果确定所述网页浏览请求是否受到网络攻击，包括：
首先、根据所述攻击规则与所述域名解析信息，确定所述域名解析信息中包含的IP地址的合法性。
然后、根据所述域名解析信息中包含的IP地址的合法性，确定所述网页浏览请求是否受到网络攻击，其中，若所述IP地址合法，则确定所述网页浏览请求未受到网络攻击，若所述IP地址非法，则确定所述网页浏览请求受到网络攻击。
通过上述操作，能够基于域名解析信息中包含的IP地址的合法性，确定网页浏览请求是否受到网络攻击。
另外，参见图3，所述根据所述攻击规则与所述域名解析信息，确定所述域名解析信息中包含的IP地址的合法性，包括以下步骤：
步骤S121、通过所述网页浏览请求，获取所述攻击规则中的目标攻击规则，其中，所述攻击规则中包含域名、IP地址和规则类型标识，所述目标攻击规则包含的域名与所述网页浏览请求待访问的域名相同。
其中，所述攻击规则中包含的规则类型标识用于表明该域名对应下的 IP地址是否合法，若所述规则类型标识为合法标识，则确定该域名对应的IP地址合法，若所述规则类型为非法标识，则确定该域名对应的IP地址非法。
步骤S122、遍历所述目标攻击规则，确定所述域名解析信息中包含的IP地址是否包含在所述目标攻击规则中，若是，执行步骤S123的操作，若否，执行步骤S124的操作。
步骤S123、若所述域名解析信息中包含的IP地址包含在所述目标攻击规则中，判断所述域名解析信息中包含的IP地址在所述目标攻击规则中对应的规则类型标识是否为合法标识，若是，执行步骤S124的操作，若否，执行步骤S125的操作。
步骤S124、确定所述IP地址合法。
步骤S125、所述域名解析信息中包含的IP地址在所述目标攻击规则中对应的规则类型标识为非法标识，确定所述IP地址非法。
上述步骤S121至步骤S125，公开一种根据攻击规则与域名信息，确定域名解析信息中包含的IP地址的合法性的方法。该方法中，在获取目标攻击规则后，若所述域名解析信息中包含的IP地址并未包含在所述目标攻击规则中，则确定所述域名解析信息中包含的IP地址合法，或者，若域名解析信息中包含的IP地址包含在所述目标攻击规则中，则进一步根据所述目标攻击规则确定所述域名解析信息中包含的IP地址是否合法，其中，若所述域名解析信息中包含的IP地址在所述目标攻击规则中对应的规则类型标识为合法标识，则确定所述IP地址合法，若所述域名解析信息中包含的IP地址在所述目标攻击规则中对应的规则类型标识为非法标识，则确定所述 IP地址非法，从而能够根据攻击规则与域名解析信息，确定域名解析信息中包含的IP地址是否合法，以便根据所述IP地址是否合法，来确定网页浏览请求是否受到网络攻击。
其中，所述攻击规则可以为多种形式。在其中一种形式中，所述攻击规则的形式为：“域名|规则类型|IP地址”。其中，“|”起到分隔作用，规则类型可采用“0”和“1”，其中，“0”为非法标识，“1”为合法标识。当然，所述攻击规则还可以为其他任意包含有域名、规则类型和IP地址的形式，本申请对此不做限定，并且，规则类型包含合法标识和非法标识两种类型，这两种标识也可采用其他字符，本申请对此不做限定。
在以下陈述中，以一个攻击规则的具体实例说明根据攻击规则与域名解析信息，确定网页浏览请求是否受到网络攻击的工作流程。
在该攻击规则的示例中，设定其中一条攻击规则为“m.baidu.com|1|61.135.185.17”，另一条攻击规则为“m.baidu.com|0|61.135.185.18”，“0”为非法标识，“1”为合法标识，而网页浏览请求待访问的网页为百度网站，在获取网络根据网页浏览请求返回的域名解析信息后，获取攻击规则中的目标攻击规则，其中，所述目标攻击规则为包含有“m.baidu.com”这一域名的攻击规则，这种情况下，“m.baidu.com|1|61.135.185.17”和“m.baidu.com|0|61.135.185.18”均为目标攻击规则；然后，判断域名解析信息中包含的IP地址是否包含在各条目标攻击规则中，若所有目标攻击规则中均不包含所述域名解析信息中包含的IP地址，则确定所述域名解析信息中包含的IP地址合法，该网页浏览请求未受到网络攻击；若所述域名解析信息中包含的IP地址为 “61.135.185.17”，由于在目标攻击规则中，该IP地址对应的规则类型标识为合法标识，则确定该域名解析信息中包含的IP地址合法，网页浏览请求未受到网络攻击；若所述域名解析信息中包含的IP地址为“61.135.185.18”，由于在目标攻击规则中，该IP地址对应的规则类型标识为非法标识，则确定该域名解析信息中包含的IP地址是非法的，网页浏览请求受到网络攻击。
另外，浏览器客户端接收到的攻击规则往往有多条。其中，一个域名对应的攻击规则可能包含多条，这种情况下，同一域名对应的攻击规则可设置为“域名|规则类型1|IP地址1|规则类型2|IP地址2……|规则类型n|IP地址n”的形式，如“m.baidu.com|1|61.135.185.17|0|115.239.210.14”，这一攻击规则表示，若网页浏览请求待访问的域名为“m.baidu.com”，则解析出的“61.135.185.17”这一IP地址是合法的，解析出的“115.239.210.14”这一IP地址是非法的。
另外，不同域名的攻击规则可设置在一起，并采用分隔符隔开，例如，可设置成“域名1|规则类型1|IP地址1^^域名2|规则类型2|IP地址2……^^域名n|规则类型n|IP地址n”，其中“^^”为隔离不同域名的攻击规则的分隔符，当然，还可以选用其他形式的分隔符，本申请对此不做限定。这种情况下，“m.baidu.com|1|61.135.185.17|0|115.239.210.14^^m.sogou.com|0|202.91.232.39”这一攻击规则表示，若网页浏览请求待访问的域名为“m.baidu.com”，若域名解析信息中包含的IP地址为“61.135.185.17”，则该IP地址合法，网页浏览请求未受到网络攻击，若域名解析信息中包含 的IP地址为“115.239.210.14”，则该IP地址非法，网页浏览请求受到网络攻击。相应的，若网页浏览请求待访问的域名为“m.sogou.com”，且域名解析信息中包含的IP地址为“202.91.232.39”，则该IP地址非法，网页浏览请求受到网络攻击。
另外，若通过所述网页浏览请求，无法获取攻击规则中的目标攻击规则，也就是说，在攻击规则中，不存在目标攻击规则，这种情况下，通常认为所述域名解析信息中包含的IP地址合法，网页浏览请求未受到网络攻击。
上述内容介绍了通过检验域名解析信息来判断是否收到网络攻击，此外，如图4所示，当通过响应信息来判断是否受到网络攻击时，所述将预先获取的攻击规则与所述反馈信息进行匹配对比，根据对比结果确定所述网页浏览请求是否受到网络攻击，包括：
步骤S131、通过所述网页浏览请求，判断攻击规则中是否存在目标攻击规则，若是，执行步骤S132的操作，若否，执行步骤S135的操作。其中，所述攻击规则中包含篡改关键字、篡改前的信息表达式和篡改后的信息表达式，所述目标攻击规则包含的所述篡改前的信息表达式与所述网页浏览请求相对应。
步骤S132、若确定所述攻击规则中存在目标攻击规则，在获取所述目标攻击规则后，遍历所述目标攻击规则，判断所述响应信息中的响应头关键字是否与所述目标攻击规则中的篡改关键字相匹配，若是，执行步骤S133的操作，若否，执行步骤S135的操作。
所述响应信息包括响应头和响应头主体，并且，所述响应头由响应头 关键字和响应头内容构成。
另外，根据网络攻击类型的不同，篡改关键字不同。例如，若本次网络攻击是将网页浏览器对应的网址重定向至另一网址，以使浏览器客户端浏览被重定向后的网址，这种情况下，篡改关键字往往为“location”等字段。“location”等字段可以表示在网络攻击的类型为网址重定向时，网络浏览请求被重新定位到的网络地址。通常情况下，若所述响应头关键字中包含有该篡改关键字，则认为响应信息中的响应头关键字与所述目标攻击规则中的篡改关键字相匹配。
步骤S133、若所述响应信息中的响应头关键字与所述目标攻击规则中的篡改关键字相匹配，判断所述响应信息中的响应头内容是否与该条目标攻击规则中的篡改后的信息表达式相匹配，若是，执行步骤S134的操作，若否，执行步骤S135的操作。
步骤S134、若所述响应头内容与该条目标攻击规则中的篡改后的信息表达式相匹配，确定所述网页浏览请求受到网络攻击。
其中，所述篡改后的信息表达式与所述篡改前的信息表达式不相同。
步骤S135、确定所述网页浏览请求未受到网络攻击。
通过步骤S131至步骤S135的操作，能够根据攻击规则与反馈信息，确定网页浏览请求是否受到网络攻击。根据上述操作可知，攻击规则中包含有篡改关键字、篡改前的信息表达式和篡改后的信息表达式，若某一攻击规则中，篡改前的信息表达式与网页浏览请求相对应，篡改关键字与所述响应信息中的响应头关键字相匹配，并且篡改后的信息表达式与响应信息中的响应头内容相匹配，则说明本次网页浏览请求受到网络攻击。
根据网络攻击的类型的不同，信息表达式也包括多种类型。例如，所述信息表达式为：URL地址表达式、渠道号表达式或媒体类型表达式，或者，所述信息表达式也可以为其他类型，本申请对此不做限定。
若篡改前的信息表达式和篡改后的信息表达式均为URL地址表达式，则说明受到网络攻击后，网页浏览请求的访问地址被重定向至其他的URL地址；若篡改前的信息表达式和篡改后的信息表达式均为渠道号表达式，则说明受到网络攻击后，网页浏览请求中的渠道号被篡改；若篡改前的信息表达式和篡改后的信息表达式均为媒体类型表达式，则说明受到网络攻击后，网页浏览请求中的媒体类型表达式被篡改。
例如，网页浏览请求表明本次待访问的网页页面为百度网站的页面，则目标攻击规则中包含的篡改前的信息表达式包含百度网站的URL地址，若响应头信息中的响应头关键字包含重定向关键字，所述响应头内容中包含的URL地址为其他网页的URL地址，并且与目标攻击规则中包含的篡改后的URL地址相匹配，则可以确定网页浏览请求受到网络攻击，网页浏览请求被重定向至其他网页页面，浏览器将无法访问百度网站。
在以下陈述中，以一个攻击规则的具体实例说明根据攻击规则与反馈信息，确定网页浏览请求是否受到网络攻击的工作流程。
在该攻击规则的示例中，设定该攻击规则为“rescode|301|location|.*m.baidu.com.*from＝1009719a|location|.*m.sogou.com.*”，其中，“rescode”、“301”和“location”为篡改关键字，“.*m.baidu.com.*from＝1009719a”为篡改前的信息表达式，“.*m.sogou.com.*”为篡改后的信息表达式，该信息表达式为URL(Uniform  Resource Locator，统一资源定位符)地址，并用“|”分隔，其中，“rescode”为“response code”的简写，表示网页浏览请求的服务器返回代码，“301”和“location”表示重定向，“.*m.baidu.com.*from＝1009719a”表示受到网络攻击前，浏览器客户端的目的是要访问百度网站，“.*m.sogou.com.*”表示受到网络攻击后，浏览器客户端被重定向至访问搜狗网站。
另外，本申请的第二实施例中，公开一种安全的网络数据传输方法，该方法应用于浏览器客户端。参见图5所示的工作流程示意图，所述安全的网络数据传输方法包括：
步骤S21、获取网络根据网页浏览请求返回的反馈信息。
当用户需要访问浏览器时，会对所述浏览器进行操作，如触控所述浏览器等，所述浏览器在接收到操作后，会产生相应的网页浏览请求，并由网络根据所述网页浏览请求返回相应的反馈信息。所述反馈在网络传输过程中，往往会受到网络攻击，导致所述浏览器客户端无法获取正确的反馈信息。网络攻击可能发生于网络中的不同节点，则所述反馈信息可以，但不限于为域名解析信息和网络根据所述网页浏览请求返回的响应信息。例如，若需要浏览网页，浏览器客户端会根据用户网页浏览请求的操作产生网页浏览请求，在将所述网页浏览请求传输至网页服务器之前，需要获取域名解析服务器对所述网页浏览请求的域名解析信息。所述响应信息可以由目标服务器返回，例如，若需要浏览网页，浏览器客户端会产生网页浏览请求，并将所述网页浏览请求传输至目标服务器，在传输过程中，网络会返回所述网页浏览请求对应的响应信息。
步骤S22、将获取到的攻击规则与所述域名解析信息进行匹配对比，根据对比结果确定所述网页浏览请求是否受到网络攻击，其中，所述攻击规则是由规则配置服务器发送的。
当通过检验域名解析信息来判断是否受到网络攻击时，所述将预先获取的攻击规则与所述反馈信息进行匹配对比，根据对比结果确定所述网页浏览请求是否受到网络攻击时，可首先根据步骤S121至步骤S125的方法确定域名解析信息中包含的IP地址的合法性，然后再根据IP地址的合法性，确定网页浏览请求是否受到网络攻击，此处不再赘述。此外，当通过检验反馈信息来判断是否受到网络攻击时，所述将预先获取的攻击规则与所述反馈信息进行匹配对比，根据对比结果确定所述网页浏览请求是否受到网络攻击的方法，可参见步骤S131至步骤S135，此处不再赘述。
步骤S23、确定所述网页浏览请求受到网络攻击，则通过安全方式进行网络数据的传输。
上述步骤S21至步骤S23公开一种安全的网络数据传输方法，该方法中浏览器客户端在获取网络根据网页浏览请求返回的反馈信息后，将预先获取的攻击规则与所述反馈信息进行匹配对比，根据对比结果判断网页浏览请求是否受到网络攻击，并在根据对比结果，确定网页浏览请求受到网络攻击后，通过安全方式进行网络数据的传输；若根据对比结果，确定网页浏览请求未受到网络攻击，则按照传统技术进行网络数据的传输。通过安全方式进行网络数据的传输，能够避免网络攻击的侵害，从而解决现有技术中存在的，受到网络攻击后，网页浏览请求被篡改的问题，并且，能够减少安全隐患。
例如，当浏览器客户端在获取网络根据网页浏览请求返回的域名解析信息后，将预先获取的攻击规则与所述域名解析信息进行匹配对比，根据对比结果判断网页浏览请求是否受到网络攻击，并在根据对比结果，确定网页浏览请求受到网络攻击后，通过安全方式进行网络数据的传输；若根据对比结果，确定网页浏览请求未受到网络攻击，则根据域名解析信息获取待访问的IP地址，访问IP地址对应的目的服务器，进行网络数据的传输。通过安全方式进行网络数据的传输，能够避免网络攻击的侵害，从而解决现有技术中存在的，受到网络攻击后，浏览器客户端无法获取到正确的IP地址，进一步导致浏览器客户端无法获取所需的网页数据，导致用户无法浏览所需的信息的问题，能够使浏览器客户端显示网页浏览请求对应的网页数据，满足用户的浏览需求。
进一步的，步骤S23中所述的通过安全方式进行网络数据的传输，包括以下步骤：
首先，浏览器客户端将所述网页浏览请求加密后发送至代理服务器，以供所述代理服务器解密加密后的网页浏览请求后，对解密后的网页浏览请求进行域名解析，并访问与域名解析结果相对应的目标服务器，获取与所述解密后的网页浏览请求对应的网络数据，并且加密所述网络数据。
然后，接收所述代理服务器返回的加密后的网络数据。
浏览器客户端和代理服务器之间预先设置有私有协议，即预设协议，通过所述预设协议能够规定浏览器客户端和代理服务器之间的加解密方法。浏览器客户端根据与网络代理服务器之间的预设协议对网页浏览请求进行加密，并将加密后的网页浏览请求传输至代理服务器。所述代理服务 器在获取所述加密后的网页浏览请求后，根据预设协议进行解密，并在获取解密后的网页浏览请求后，对解密后的网页浏览请求进行域名解析，访问域名解析结果对应的目标服务器，在获取网络数据后，所述代理服务器根据预设协议加密所述网络数据，并将加密后的网络数据传输至浏览器客户端。所述浏览器客户端接收到加密后的网络数据后，根据预设协议对其进行解密，并显示解密后的网络数据，以便用户浏览。
由于浏览器客户端和代理服务器之间传输的数据经过加密，因此不会受到网络攻击的影响，从而能够使浏览器客户端获取到正确的网页数据。
另外，浏览器客户端在接收到所述规则配置服务器传输的攻击规则后，还可以对接收到的攻击规则进行格式解析，若经过格式解析，确定接收到的攻击规则不符合预设格式，则丢弃不符合预设格式的攻击规则。
例如，若每条攻击规则的形式设置为“域名|规则类型|IP地址”，浏览器客户端判断规则配置服务器传输的攻击规则若符合上述预设格式，若符合，则存储该条攻击规则；若不符合，则丢弃该条攻击规则，以节省存储空间。此外，在其中一种实现形式中，还可以设置每条攻击规则的格式为“key1|rule1|key2|rule2|keyn|rulen”的形式，n为自然数。若一条攻击规则为：“rescode|301|location|.*m.baidu.com.*from＝1009719a|location|.*m.sogou.com.*”，该条攻击规则表示，将访问“baidu.com”的网页浏览请求重定向至“sogou.com”这一目的地址。在该条攻击规则中，key1为rescode，rule1为301，key2为location，rule2为“.*m.baidu.com.*from＝1009719a”，key3为location，rule3为 “.*m.so.com.*”，并采用“|”进行间隔，则认为该条攻击规则符合格式。
这种情况下，浏览器客户端在接收到规则配置服务器传输的攻击规则后，判断该条攻击规则是否符合“key1|rule1|key2|rule2|keyn|rulen”的形式，若符合，则存储所述攻击规则，若不符合，则丢弃该条攻击规则，以节省存储空间。当然，在其他实现形式中，所述攻击规则还可以设置为其他的多种形式，如“key1：rule1；key2：rule2；keyn：rulen”等，本申请对此不做限定。
进一步的，本申请公开的所述安全的网络数据传输方法还包括：确定所述网页浏览请求受到网络攻击后，丢弃所述域名解析信息。
若网页浏览请求受到网络攻击，浏览器客户端接收到的域名解析信息会受到网络攻击的影响。例如，所述域名解析信息为网络根据所述网页浏览请求返回的域名解析信息，则所述域名解析信息中包含的IP地址往往是错误的。因此，丢弃所述域名解析信息，从而减少存储空间。
以下以多个具体例子描述本申请的优势：
在现有技术中，浏览器客户端在需要浏览百度网站时，有时会受到网络攻击，接收到错误的域名解析信息，所述错误的域名解析信息中包含的IP地址为360网站的IP地址。例如，浏览器客户端和域名服务器之间的一个网络节点发生DNS劫持，把域名解析服务器解析出的“m.baidu.com”这一域名对应的IP地址修改为360网站的IP地址。这种情况下，所述浏览器客户端会访问所述360网站。本申请公开的安全的网络数据传输方法，会根据攻击规则确定网页浏览请求受到网络攻击，从而通过安全方式进行网络数据的传输，使浏览器客户端能够访问到正确的百度网站。
另外，为了便于对比，浏览器客户端在接收到攻击规则后，可对攻击规则进行解析，使每条攻击规则形成如图6所示的数据结构，该数据结构为一种二维的数据结构。该二维的数据结构中，将各个域名作为索引，用于指示各个域名的规则列表。为了能够应对多种类型的攻击规则，规则配置服务器根据浏览器的访问需求配置有多条攻击规则，例如，浏览器在访问百度网站时，可能会碰到跳转至360网站或其他广告网站的网络攻击；浏览器在访问某一购物网站时，可能会碰到跳转至其他购物网站的网络攻击。规则配置器据此配置多条攻击规则，浏览器客户端在接收到该攻击规则后，可根据各条攻击规则包含的域名,将攻击规则解析为图6所示的二维的数据结构。
本申请公开的针对网络攻击的防护方法能够应用于多种应用场景，对多种类型的网络攻击进行防护。
在其中一种应用场景中，网络攻击使网页浏览请求中的目的地址被篡改，使其被重定向至非法目的地址。在现有技术中，浏览器客户端只能去访问被重定向的所述非法目的地址。而在本申请中，浏览器客户端能够识别该网络攻击，通过代理服务器获取所需的网页数据。例如，若该次网络攻击将访问百度的网页浏览请求，被重定向至访问360网站，这种情况下，响应信息中的响应头中包含如“301”或“302”，以及“location”等重定向字段，并包含有360网站的URL地址。浏览器客户端在接收到网络返回的响应信息后，根据网页浏览请求中包含的待访问的目的地址，及百度的URL地址，查找攻击规则中的目标攻击规则，其中，所述目标攻击规则中包含的篡改前的URL地址表达式与网页浏览请求中包含的百度的URL地址相对 应；然后，遍历目标攻击规则，判断响应头信息中的响应头关键字中是否与各条目标攻击规则中的篡改关键字相匹配，所述篡改关键字即为“301”或“302”，以及“location”等重定向字段。若响应信息中的响应头关键字与某一条或某几条目标攻击规则中的篡改关键字相匹配，则继续判断响应头内容是否与该目标攻击规则中的篡改后的信息表达式相匹配，篡改后的信息表达式为被重定向后的网站地址，在该例中，所述篡改后的信息表达式为360网站的URL地址，在所述响应头内容与该条目标攻击规则中的篡改后的信息表达式相匹配的情况下，则确定所述网页浏览请求受到网络攻击，网页浏览请求被篡改，使其重定向至360网站，需要通过安全代理服务器获取所需的网页数据，从而避免了网络攻击的影响。
在另一种应用场景中，一些非法运营商将正常的网页浏览请求重定向至自己的广告页面。现有技术中，浏览器只能够访问该运营商的广告。而本申请中，浏览器客户端能够识别这种状况，获取所需的网页数据。例如，造成印度尼西亚白屏的原因,就是因为运营商进行网络攻击，将用户正常的网页浏览请求，跳转到一个广告页面，而该广告加载比较慢，会有十几秒的白屏，从而出现白屏情况。这种情况下，若某一条或某几条攻击规则中包含的篡改前的URL地址表达式为网页浏览请求对应的目的地址，响应头关键字与其中一条目标攻击规则中的篡改关键字相对应，均包含“301”或“302”，以及“location”等重定向字段，并且，响应头内容与该条目标攻击规则中的篡改后的信息表达式相匹配，均对应到该广告页面的URL地址，则确定网页浏览请求被重定向至广告页面，受到网络攻击，需要通过安全代理服务器获取所需的网页数据，从而使浏览器客户端显示正常的网 页数据，减少印度尼西亚的白屏情况。
在另一种应用场景中，一些非法商户在某些网络节点篡改网页浏览请求中包含的渠道号，达到自己盈利的目的。现有技术中，浏览器客户端只能任由渠道号被篡改，而本申请中，浏览器客户端能够识别这种状况。例如，某些商户将浏览器客户端访问百度的渠道号“from＝2001c”改为该商户自己的渠道号，这种情况下，若某一条或某几条攻击规则包含的篡改前的渠道号与该网页浏览请求中包含的渠道号相同，则确定该攻击规则为目标攻击规则，若响应信息的关键字与其中一条目标攻击规则中的篡改关键字相匹配，且响应头内容与该目标攻击规则中的篡改后的渠道号表达式相匹配，则确定本次网页浏览请求受到网络攻击，需要通过安全代理服务器获取所需的网页数据，从而避免了网络攻击的影响。
