asp.net - How do I control reloads when using the back button in the browser? -

-

I have an ASP.NET application that has a heavily major page; the contents of this main page are seldom changed Apart from the action taken on the same page.

When I retrieve the browser from the cache by pressing the "back" button in the user browser, to contact the server every time, is it being forced to render this page again?

Thanks, Jonas

The short answer is: You can not.

I think the closest you can do is to include something related to your webpage, especially caching and termination like: 

  & Lt; Meta HTTP-equivalent = "EXPIRES" content = "[some date / time in the future]" & gt;

and 

  & lt; Meta HTTP-EQUIV = "cache-control" content = "public" & gt;

Once you are sent to the client browser in the web page provided to you, then you just hope the browser, on the user who clicks the back button, on one of your web servers Rather than inciting another request / reaction cycle, the "cached" version of your page, to which your web page can be re-requested and re-presented. Although you will not have any control over it, and it is completely below how the browser wants to handle it, I believe most modern browsers will request the page again, however.

ASP.NET Another way to prevent re-rendering of the page is to control it on the server-side

Instructions within your ASP.NET web page, like this: 

  & lt;% @ OutputCache period = "600" VaryByParam = "none"%>

This is the most basic, @Output cache control will cache your provided ASP.Net page for a certain number of seconds (above 600 examples) so that after that page Will result in the ASP.NET runtime, rather than the user re-rendered version of the page, re-processing and re-submitting the whole page. Keep in mind that this is not user-specific, though.

More information about page output caching (which is probably the closest, what will you do afterwards):

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

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...
