I found this on the web and thought the information would be useful.

Updated to v0.4b

This should be enough code for anyone to develop further.

Can you help, add a feature to connect over another proxy?

I tried the modified version posted by Ka36ek at '?do=embed' frameborder='0' data-embedContent>>.

After found the Base64.au3 to included. I got it to authenticated successfully on the other proxy server but returned blank display on internet explorer or firefox.

stalliont,

Are you planning on running a local proxy server to an external proxy,

permanently?

I personally have not attempted it, nor do I have a need for an external proxy,

so I have nothing to test with to see if it is working properly or not.

Can you elaborate why you need an external proxy with this script?

Do you know for sure that the proxy only accepts a Base64 Encoded login?

I ask these questions out of curiosity - so I might contemplate how to go

about it and be stable - and to find out what your goal is concerning it.

stalliont · October 8, 2014

hi ripdad, thanks for quick reply.

I am trying to setup this local proxy under coorporate network and the only way to get to internet is through this proxy. Once i can get this working. Then my next step to run on a server with set commands for user can choose for automated reporting as we have different external websites that need to get source data for manipulation.

Ah 'Base64 Encoded login' you mentioned might be the culprit. I might starting checking which encode type login the proxy is using could fix my problem.

It could be better to have this with your version of proxy server as its so simple and clean.

ripdad · October 8, 2014

The next question would be - is the corporate proxy a 1:1 pass-through type

or does it handle https connections separately, etc?

The reason I ask this is because the local proxy server discards the initial

request after it has connected to the host server. (Line: 237)

Afterwards, it passes the following requests to the host as they are received.

It seems to me that there would have to be some inter-action here to make

a secure connection. If this is the case, then the script would have to

be modified to handle it.

-edit-

The script would also need to know how the corporate proxy responds

if a connection could not be made, etc.

hi ripdad, thanks for answering my queries. I got the autenticate working, connecting thru my corporate proxy using http, but https would not work, getting an error bad request.

Things getting a little more technical trying to find out how my corporate proxy works handling https

Here is an example log connect to https://www.yahoo.com, as what you are saying that you are probably right about my corporate proxy handling https connection differently not 1 on 1 passthru.

I think I just play around and do my codes with http connection, and troubleshoot https on the other thread for 'autoit proxy server',

but i like your continued work with the local proxy server, and the TCP Passive Proxy Filter, these are great alternatives...

ripdad · October 10, 2014

Glad to hear you got the http authentication working.

Good luck to you with the https part of it.

ripdad · October 22, 2014

Updated first post to v0.5b

ripdad · October 29, 2014

Updated first post to v0.6b

stalliont,

I think I found your https problem with the corporate proxy -- refer to first post update notes.

From your log,

Host: www.yahoo.com:443 --> HTTP/1.1 400 Bad Request ( The data is invalid. )

dmob · November 2, 2014

Thank you for your dedicated work on this code...

ripdad · November 3, 2014

You are most welcome -- although "dedicated" might be too strong a word.

ripdad · November 18, 2014

Updated first post to v0.7b

Fire · November 22, 2014

Very nice job && Respect!

ripdad · September 21, 2015

Thanks Fire.

Have not had the time to work on it till recently. Made some changes and improvements.

If anyone has any issues with it, Now would be a good time to voice them.

Will update soon.

ripdad · September 22, 2015

Updated to v012b -- see first post.

tbwalker · January 19, 2016

I just downloaded the v012b update and I must be doing something wrong. When I attempt to execute or compile it, I get a syntax error on line 41 (screenshot attached).

The error appears below line 41 and reads:

Local Const Enum $PortNumber, $ClientSocket, $RemoteSocket, $ProtocolState, $RemoteHost, $RemoteIP, $ContentLength, $ReceivedBytes, $RemoteClose, $Inactivity
error: syntax error
error: Statement cannot be just an expression.

I'm running AutoIt v3.3.14.0

Any help or tips on what I might be doing wrong with the script would be greatly appreciated.

Thanks,

TBWalker

BrewManNH · January 19, 2016

Remove the Const part of that line, Enums are already constants, so it's redundant anyways.

tbwalker · January 20, 2016

Thank you !
