[Proposal]: Add Http proxy support.

[mike820324]

Adding HTTP Proxy Support. There may be two cases when firefox is configured as http proxy,

Survey:

Firefox Behavior:

• Same Protocol (HTTP Proxy to HTTP site): The query message would be something like the following message.

GET http://www.google.com HTTP/1.1\r\n
...

• Different Protocol(HTTP Proxy to HTTPs site): Firefox will use CONNECT method to deal with it.

CONNECT https://www.google.com HTTP/1.1\r\n
User-Agent: xxx
Proxy-Connection: keep-alive
Connection: keep-alive
Host: www.google.com:443\r\n\r\n

The following curl command serve the same functionality.

curl --proxy http://127.0.0.1:5580 http://www.google.com
curl --proxy http://127.0.0.1:5580 https://www.google.com

P.S curl also has the proxytunnel option, which will force all the query to use connect instead.

curl --proxy http://127.0.0.1:5580 --proxytunnel http://www.google.com

curl --proxy http://127.0.0.1:5580 http://www.google.com
curl --proxy http://127.0.0.1:5580 https://www.google.com

Maybe you mean

curl --proxy http://127.0.0.1:5580 https://www.google.com
curl --proxy http://127.0.0.1:5580 --proxytunnel https://www.google.com

Yes, the proxytunnel options will force curl to use CONNECT in every protocol.

The above comment that I want to describe is how http client such as curl and firefox handle http proxy in different situations. :)

So if one want to check the CONNECT method, either

• using http proxy connect to https website

or

• use proxytunnel instead.

If one want to check the other way,

• using http proxy connect to http website should create this issue.

Sorry for the misunderstanding.
