http - How can I detect if page was requested via a redirect? -

-

Loads of redirects that go to a particular page on a customer's website. This page should know in any way whether the request was direct (URI is manually typed) or redirect.

  1. All redirects are 301 redirects. Due to SEO regulations, the added indicators should be avoided. (Google with different values ​​to the URL)

  2. I have tried to check all the environment variables, but all of them are empty (which is normal) and There is no internal redirection in this regard, I think differently (I think).

  3. Detection needs to be real time, so log files are not an option. In a nutshell process, parameters are registered in cookies through a script, then it is redirected to 301 on the page where the content cookie is operated.

    I hope this makes sense.

    Previous: I was thinking about the situation when the content is registered, the content will not change back to the original. Code, but I'm not sure whether there is any way to read on the destination page. (We have made it clear that this will not work)

Based on browser and intermediate proxy, many Things may happen, however, in most cases you can not depend on anything. The status code is something that sends back to the server browser, so you will not get them on request.

You do not say that you are trying to solve the problem or why it is important

rather than depending on what you are not controlling Change it to something that you can control.

  1. Ensure that you're redirecting the right kind.

  2. If you do not need data in real time, you can find out from log files. It's easy if you are trying to detect traffic patterns, but are not so useful in real time.

  3. Instead of external redirection, it creates internal redirection, you can track it through the request cycle of your web server.

  4. Set a cookie on external redirection and then look for it in the request. It will not catch people who do not set cookies.

  5. Add path information for redirection or add query parameters as suggested by Cena.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
