I need loging all HTTP request (from any application).
I have Delphi 7.0.
Anybody know how do that?
I looked into whether the Indy components could do this but found an old newsgroup response from Remy Lebeau that said:
If...you want to look at the traffic
that other applications are
generating, then no, you cannot use
Indy for that. That is outside the
scope of what Indy is designed for.
You would have to write your own NDIS
driver for that kind of capturing. Or
use a third-party sniffer API, such as
WinPCap.
What about WireShark?
There is also a product called Fiddler. I have found this extremely useful to track down exactly what the Indy components are sending/receiving. The one drawback is you have to utilize a proxy. This isn't a problem with Indy components and browsers such as Firefox. But if you need to capture for all applications you would need to be able to set a proxy for those apps.
if you want to go deeper and want pure delphi thing, there is winsock logger program floating around, google might help you ( it hooks winsock apis though).
Do you have to write a Delphi app to do it? Could you use an application like ethereal?

I am currently working on an application which have to determine the type (CONNECT, Socks4, Socks5 etc.) of one or more given proxies and connect through them.
Unfortunately I have no approach to reach my goals and hope somebody can help me.
I saw in a tool (GSA SEO Indexer) that this bahvior is somehow possible. The tool has a built-in proxy finder and checker which is able to determine the proxy type:
I am using Delphi XE7 w/ Indy.
There are proxy detection protocols available, such as WPAD. You can use that to obtain details about proxies on a WPAD-enabled network, and then you can connect to them as needed.
I am working on a project I intended as an academic exercise for myself. What I am basically doing is trying to add a custom compression type between an IIS server and a web browser, but getting mired in the browser aspects of it. What is basically needed is to be able to alter the byte stream on the server before it is sent to the client, and on the client browser side, be able to alter received response byte stream before other normal DOM parsing and such take place. On the server side this turned out to be pretty trivial, but I am at a loss in how to do this in chrome or firefox. If anyone has insight for chrome, please share, but I'll focus on Firefox for now. My understanding is that previously Firefox had rather low level access available to extensions but that they are tightening the restrictions a bit going forward with their Firefox add-on sdk. I don't want to bother learning the old methods if they are slated to be removed so does anyone definitively know if the add-on sdk allows you to alter the byte stream directly in this manner? If so, do you have an example of such usage?
(I am aware that I need to have the compression negotiated with the Accept-Encoding header)

There are no plans now, or in the future, to remove legacy add-on support. At least that's what add-on SDK folks and extension manager folks told me repeatedly.
Back to your question: The add-on sdk does not provide an explicit API for stuff like this, but you can always go even more low-level, even in the SDK (via the chrome module and/or window/utils).
To implement additional compression methods, you'd need to implement the nsIStreamConverter interface and properly register your component under the #mozilla.org/streamconv;1#?from=<yourcompression>&to=uncompressed contract. Then Firefox should be able to decode yourcompression.
See https://developer.mozilla.org/ for more information on how to implement and register XPCOM components in either javascript or C++.
Using the SDK or implementing your add-on restartless will require you register the component yourself instead of relying on chrome.manifest. There are a couple of add-on doing so already, e.g. Adblock Plus.
Binary (C++) components should be avoided because you'll obviously need to compile your component for each supported platform and you'll need to re-compile it for each Gecko version. If you have to go binary, a javascript component stub + js-ctypes might be better.
See the mozilla source code on how to implement nsIStreamConverter in the first place.
You may also need to modify the network.http.accept-encoding preference so that the compression may be actually negotiated with the server.
I'm new to iOS, have been developing in Delphi for many years.
I don't know FPC well and i find it very hard to figure out which classes are available on iOS.
is there any FireMonkey classes for calling web services and parsing xml?
Yes you can call a webservice :)
No it is not simple :(
You need to access the iOS framework directly...
The following code fragments will help...
First a pascal example of how to send/receive data via TCP

Secondly, you will need to wrap the call using the relevant headers. See...

It is a fair bit of work, but it can be done. Good luck!
You can also try to use RealThinClient (RTC) SDK to allow your Delphi XE2 FireMonkey iOS client to connect to a RTC SDK server. Not SOAP, but I've managed to send data back and forth between the two layers (just in case you do not have to use SOAP, but are merely looking for some way to connect an iOS client to a server)...
I am trying to build a very simple driver. Its sole purpose will be to register "PsSetCreateProcessNotifyRoutine" and on callbacks recieved from kernel, notify my Win32 application about which proccesses are started and stoped.
I only know how to build such a simple driver with "DriverEntry" and "DriverUnload" and compile it with DDK. But I don't know how to actually implement communication. I know it can be done with IOCTL. But beyond that I am in the dark. I cannot find simple example of how to do that in Delphi. I only know it can be done.
So what I am looking for is some simple and understandable tutorial on how to do it or event better an example delphi program with acompaniying driver code. Maybe there are even other ways of communication.
Any help would be appriciated.
Doesn't matter if in Delphi or not. You have to use the function DeviceIoControl. Read the article in MSDN about it.
In short, you'll have to choose some IOCTL codes from the available set. Then you call DeviceIoControl with one of these codes and pass some data, and in driver you handle that request and return something else.
You can also handle standard IOCTLS, such as the ones generated by calling ReadFile or WriteFile in user-mode.
Don't look for a "tutorial how to do that in Delphi", just look for any tutorial. They're all the same, no matter the language, it's pure Win32/Native api stuff. Here's one for example, just googled it out.
Does anyone have experience integrating SmartCard authentication in their Win32 apps? If so, are there any preferred libraries?
Try SecureBlackbox, A component that works fine for me, a second choice can be
Delphi PC/SC SmartCard Component 0.91.
try
Well I guess that you have an SmartCard reader ... if so (and if you don't have one I don't know how you are going to manage this) then it must have some interface, RS232, USB, TCP/IP ... any one will do.
Communication protocol usually is available at SmartCard reader manufacturer. Few lines, and you will have it working in Delphi.
You need to read the developer manual that comes with reader you're going to use. It might only use PC-SC (by MS) to communicate, if so you can use the component specified by RRUZ, however it doesn't work with D2009. Otherwise you'll need to use API provided by SDK.
