Writing a local proxy server WM6

Hi all,
I've written a proxy server in C# for my HTC Wizard running WM6 with the .NET Compact Framework. Its configured to route My Work Network through a proxy address 127.0.0.1 on port 8888. My proxy program runs a TcpListener on this port and IEMobile browser requests are sent to my proxy which goes to the web, gets each required file and returns them to the browser.
It works fine for files of the type htm, html, gif, png, jpg - but whenever a page uses css or js, it will not load the pages. Any clues as to why??
The program is simply an intermediate agent that reads and writes bytes from the browser and the remote point. Does anybody know why these different types of files never load correctly??
Please, any help or debug ideas is appreciated.
Thanks,
Nick

wow, nice.
i could really really use your source code for something im working on.
care to share?
don't worry, it's not anything im planning to publish soon, just a personal project.
and if i ever will, it will be with your full concent and you will be credited.

thank you!

Everybody who want to share their internet connection on the phone via wifi to their local network via a proxy on the phone raise their hands.

woohoo! me me me! xD
actually, it is the proxy itself that i need for other functionality. thats why i need the source code...

me too, the proxy not the source code

You alos need to do some header parsing. If you don't want to do much work, your best bet is just converting my Java language HTTP proxy to C# - it has no problems with any special files (and also supports HTTP Post). See http://www.pocketpcmag.com/blogs/index.php?blog=3&p=453&more=1&c=1&tb=1&pb=1 for the source & more info.

Thanks, Menneisyys.
I'll give it a look and hope it solves my problems. I definitely haven't done any header parsing so lets hope...
On an aside, I was wondering if anybody has any resources on the Connection Manager API for mobile device networking? I am looking for some sample code in C++ which it is native or better yet if anybody has ever ported it to C#. Or if anybody knows how to port a .h file to C#.
Any help is appreciated.
Thanks,
Nick

.pac proxy

anyway to use a .pac proxy URL on android?

don't think you can do this,think the phone os not able to understand, why do you need to use pac files?
Sent from my GT-I9000 using XDA App

I know this is old, but this is an ongoing problem and I figured out how to use a .pac proxy file! After reading about proxy's and what .pac files are, I stumbled upon a little hint and after a little tinkering I was able to use my work's wifi that uses an auto-config .pac file and my phone and tablet has full internet access with browser, apps etc including Netflix for example.
Here are the steps you need:
1) Your phone has to be rooted to take advantage of the proxy apps on the market, I personally use ProxyDroid, which is free and has a feature to bind certain proxy profiles to automatically turn on when a certain wifi network is connected.
2) Usually there is an option that gives you an http proxy pac file to manually input to your browsers or what not, so whatever the link is, put it an active internet browser to download the pac file (an example of the url with the pac file would be something like http://internet.xxxxx.com/proxy.pac)
3) Where ever you download the pac file, open it with notepad or wordpad and this will reveal all the proxy info you need in order to access the proxy enable wifi. What the ProxyDroid app needs from the PAC file is the Host url and Port number. When you open a PAC file in notepad, you'll see something like this near the top along with a bunch of other things under it:
"Cisco Remote Envelope Service
if (dstHost=="internet.e-mail") {
return "PROXY internet-x-x.xxxxxx.com:9090""
- So in "Host" under Proxy Settings in the ProxyDroid app you would input: internet-x-x.xxxx.com
- For the "Port" you would put input: 9090
4) After inputting those 2 pieces of info into the ProxyDroid app, turn the wifi on for your Android Device then enable to ProxyDroid app, you should able to connect to the proxy enabled wifi!
*Some notes for the ProxyDroid app.
- It allows for Authentication, but since my work wifi does not use that, I'm not sure how it would work
- For Proxy type, I set it as an HTTP
- I binded the specific proxy profile to my work wifi so it would ProxyDroid would automatically enable when work wifi was detected
Hope this bit of info helps other that have Android devices and were unable to use a proxy enable wifi to finally access them. Hopefully in the future, Android will make using proxy and pac files a lot easier like how it's done on the ipad where they allow you to manually set up proxy settings by having the device download the PAC file.
I've tested and this works on both a rooted AT&T HTC Inspire and a HP Touchpad running CM7 Alpha

Check out autoproxy on the market. It's my app and it's new. It's the only app that supports proxy.pac proxies directly. Just put the address to the file there, and click connect. It will also auto-connect when you're on the same network again (and disconnect when you're off it) so it's set and forget. It will allow you to use any apps, as long as the port is not blocked by the proxy.

Dtothesquare, that technique will work for simple proxy implementations but some organizations have a cluster of proxy servers that may serve different clients (closer to client without using anycast) or destinations. For example, a proxy server may be set up to just handle *.com while another could handle just internal hosts. It can also be used for sending clients to an alternate proxy server should the primary one be down for some reason.
Our proxy server has ACLs that only let it proxy certain URLs and returns an error if it receives something that's not allowed on that server.

[Q] How to take data from an online database?

Hello, I'm developing an android app that needs access to a .xml database that will be updated from time to time by various Admins.
How do I do so that, when I create a new field, it synchronized with the android application? I read about the SQLite database, but I did not understand if it can be done so that it can be changed once you have compiled the app...
PS: Sorry for my english

Firstly, you need a PHP script, or any web language script that is able to grab data from the database and echo them out on the browser.
Then your app would just need to make a HTTP request to the URL and get the data. As simple as that.
SQLite Database is Android's internal database used and created by each individual app. It has nothing to do with web's database.

XML parsing.. someone told me about it

I like the partially online/mostly offline approach... this may consume big amount of internal storage, but maybe what the OP is looking for... For accessing online database, a PHP interface is the most common, with this we can consult the online db, parse the data, insert it into the local database and work there...

You need a server side script in any laguage to fetch data from database. Then create a HTTP request to the url and get the data from online database.

[Q] Provide security while using http

How to provide security when i use http for receiving the json response from the web server and also i'm sending the user details to the server to save those details in mysql db. I'm using HTTP post.

To provide security, I think you should use HTTPS post.

What user details? if the only user important data is the password, you only need to transform it in MD5 before to send it via HTTP.
The best and strong way to make a HTTP save connection is HTTPS, but if you want to make it easy, you can encrypt the json user data string, send via HTTP post, and decrypt it in the server. There are a lot of encrypt string examples in google.

Expert opinion on HTTP header

Hi guys,
I'm working on an app at the moment but I can't get it to work.
I am trying to load a webpage by its IP address, usually this will not work because the server doesn't know what site you want to access in the case of a shared hosting etc. So I am injecting the "host domain.com" header into the request. However the page will still not load.
Anyone got an idea of how I can do this. I know I can use the host file but I'm trying to achieve it without admin privileges. on the pc.
Using wireshark the only difference I found in the packet were GET string in the HTTP header so not sure if I'm missing something..

There is no way to help you if you don't provide any sort of source code or dump of the packages you're sending.
