　　Re: NaturalJ0

　　Thanks for your suggestion, brother.
　　After thinking about it, I found that there is a -S parameter in wget that can count the detailed download information, including the connection speed. The speed is indirectly obtained through the front and back two times. If you want to sort, you must analyze the information obtained from the -S parameter, which will be relatively troublesome. Moreover, in the code at the top of the post, the time for wget to time out to obtain the web page is set to 3 seconds, so the detected speed should be acceptable. If you want a faster proxy connection speed, you can modify the value of the -T parameter.

　　Re: ccwan

　　Thanks for your encouragement, brother.

　　Re: wang6610

　　It can only detect the specified industry web proxy list. If you want to detect the proxy lists of other pages, you can manually add URLs to the batch processing. I will also try to improve it as much as possible.

It's really good, but it's a pity that it can only verify the proxy of that one website. It doesn't work when changing to another one. All the proxies of that website have become invalid. It's best to find a verification that can be updated every day. Or make the code more intelligent, so that it can deal with most proxy sites.

Modifying based on the owner's code should allow extraction. The owner's code is also much more concise and has a much smaller size...

I'm sorry, I'm replying to an old post.

Mainly I haven't understood the following sentences clearly all the time, and I hope some expert can explain them to me:

1 set set=
2 set set=%%a
3 set "set=!set:&#8205=!"
4 set "set=!set!:%%b"

Main questions:
1, Will there be no problem if the system's keyword is used as the environment variable name?
2, Why is it necessary to set it to empty once before each setting? Can the first sentence be omitted?
3, Looking at the original content of the web page:
<tr><td>202.105.182.20&#8205:80</td><td>HTTP</td><td>328,813,813</td><td>Zhuhai City, Guangdong Province</td></tr>
I don't quite understand the algorithm for intercepting the proxy address.

There is also a question, that is, when the data in the source code becomes the following form, how to take into account the two methods?
<tr><td>211.142.213.11&#8204&#8205:80</td><td>HTTP</td><td>110,7203,7203</td><td>Hunan Province, Changsha City, Mobile</td></tr>
