1. Implementation of the Agent::: General agent and reverse agent??

Common agent set up trouble, Korean reverse proxy easy to implement.

Reverse Proxy usage Process:: localhost/vod/>>url rewrite >>> content changes

2. URL Rewrite frame selection

PHP mode_rewrite Good ... java org.tuckey.web.filters.urlrewrite.UrlRewriteFilter not too good to use the,,, son good ga ...

1. Java implementation

<!--o8j2-->

<filter>

<filter-name>urlrwt</filter-name>

<filter-class>com.attilax.net.urlRewriteFilterAti</filter-class>

</filter>

<filter-mapping>

<filter-name>urlrwt</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<!--end O8j2-->

RequestDispatcher RequestDispatcher = Request.getrequestdispatcher ("/spr/txtrwt?url=" +url+ "&urlNoHost=" +url_ NOHOST2);

Requestdispatcher.forward (request, response);

4. excluding oneself (apache_mode_rewrite)

Rewritecond%{request_uri}!=/process.php

Rewritecond%{request_uri}!^.* (\.JS|\.GIF|\.PNG|\.JPG|\.JPEG|\.XML|\.ICO|\.CSS)

#other pic css JS Proxy

Rewritecond%{request_uri}!=/process.php

Rewritecond%{request_uri}!=/lensyaohwer/basic.png

Rewriterule ^ (. *) $ http://lengxiaohua.com/$1 [p,l]

2. Java implementation excludes itself

Except

if (Requesturi.contains ("SPR/TXTRWT"))

{

Chain.dofilter (request, response);

Return

5. Content Rewriting (PHP mode_rwt)

A. Text regular expression style

$content =preg_replace ('/Miss Si/', ' hammy ', $content);

$content =str_replace (' http://img.spriteapp.cn/ws/www/img/layout/logo.png ', ' http://img.spriteapp.cn/ws/www/img/ Layout/logoxx.png ', $content);

$content =str_replace (' No sis ', ' hammy ', $content);

B.html Dom Way

NbP

Require_once "simple_html_dom.php";

$html = str_get_html ($content);

$arr = $html->find (' web_content_right. Web_right_down ', 0);

$arr->innertext= ' A2 ';

Echo $html;

3. Java content rewriting

@RequestMapping (value = "/TXTRWT", produces = "text/plain;charset=gb2312")

@ResponseBody

Public Object process (HttpServletRequest request,

HttpServletResponse response) throws Exception {

Core.log ("=========process.json");

String URL = "" + request.getparameter ("url");//+ "?" +request.getquerystring ();

String url_no_host=request.getparameter ("Urlnohost");

System.out.println (); Request.getparameter ("Tid")

System.out.println (Request.getquerystring ());

if (Url.endswith ("jpg") | | url.endswith ("JPEG") | | url.endswith ("GIF")) {

if (Url_no_host.startswith ("/http://"))

{

String Url3=url_no_host.replaceall ("/http://", "http://");

byte[] ba = Websitex. Webpagecontent_bin (URL3);

if (!isljjpg (BA))

Outputimg (response, URL);

}

Else

Outputimg (response, URL);

}

//

Else

Outputtxt (response, url,request);

return null;

6. Content Rewriting---Absolute path link rewrite 4. Abs URL 2/app/http://xxxxxx.jpg

private void Outputtxt (httpservletresponse response, String URL, httpservletrequest request)

Throws Unsupportedencodingexception, IOException {

map<string, string> headprops = Mapx

. <string, String> $ ()

. Add ("Cookie",

"Lastfid=0; LASTVISIT=9271%091408838229%09%2FREAD.PHP%3FTID%3D1715718%26FPAGE%3D2; ol_offset=32204; ipstate=1408836660; __utma=99888095.1396678057.1405101634.1408806230.1408837132.29; __utmz=99888095.1405101634.1.1.utmcsr= (direct) |utmccn= (direct) |utmcmd= (none); __utmc=99888095; Pin6=done; __utmb=99888095.3.10.1408837132 ")

. Tomap ();

String Txt=websitex. webpagecontento8f (URL, "GBK", headprops);

Txt=txt.replaceall ("http://", pathx.webapppath_webfmt (Request) + "/http://");

5. Filter two times navigation

if (Url_nohost.startswith ("/http://"))

{

String url5=url_nohost.substring (1, Url_nohost.length ());

String url5_encode= Urlencoder.encode (URL5);

RequestDispatcher RequestDispatcher = Request.getrequestdispatcher ("/spr/imgrwt_abspath?url=" +url5_encode+ "& Urlnohost= "+url_nohost2);

Requestdispatcher.forward (request, response);

Return

} 6. To judge and instead of rewriting

@RequestMapping (value = "/imgrwt_abspath")

@ResponseBody

Public Object Process_imgrwt_abspath (HttpServletRequest request,

HttpServletResponse response) {

Core.log ("=========process.json");

String URL = "" + request.getparameter ("url");//+ "?" +request.getquerystring ();

String url_no_host = Request.getparameter ("Urlnohost");

System.out.println (); Request.getparameter ("Tid")

System.out.println (Request.getquerystring ());

byte[] ba = Websitex. Webpagecontent_bin (URL);

if (!isljjpg (BA))

Outputimg (response, URL);

if (isljjpg (BA))

Outputimg_garfile_holder (response);

return null;

}

/**

private void Outputimg_garfile_holder (HttpServletResponse response) {

{

String URL = pathx.classpath () + "/com/attilax/clr/def.jpg";

byte[] ba = filex.readimagedata (URL);

Outputimg (response, URL, BA);

}
