Make WinHttp.WaitForResponse() to wait more than 30 seconds

08 Aug 2015, 23:06

By default, the ReceiveTimeout of WinHttp.WinHttpRequest.5.1 is 30 seconds! Which means...
  • WinHttp.WaitForResponse(-1) ; Wait forever? No, 30 seconds max.
  • WinHttp.WaitForResponse(60) ; Wait 60 seconds? No, 30 seconds max.
To wait for more than 30 seconds, you'll need to change the default timeout, by using WinHttp.SetTimeouts(ResolveTimeout, ConnectTimeout, SendTimeout, ReceiveTimeout)

For example, modify ReceiveTimeout to 120 seconds:
WinHttp.SetTimeouts(0, 60000, 30000, 120000)
The first 3 values are the default values, see IWinHttpRequest::SetTimeouts method.

whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
whr.Open("GET", URL, true)
whr.SetTimeouts(0, 60000, 30000, 120000)
whr.Send()
whr.WaitForResponse(90)


Hope this post helps someone.

Where are you getting that? All the documentation I've been able to hastily Google is showing that it defaults to infinite and you have to set a value. This is just random Googling though, I'm not personally familiar with this.

From real testing. Try this example:

Without SetTimeouts:

Code: [Select all] [Download] GeSHi © Codebox Plus

startTime := A_TickCount
ToolTip, (Without SetTimeouts) waiting...

ComObjError(0)
whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
whr.Open("GET", "http://tmplinshi.sinaapp.com/test/timeout-test.php", true)
whr.Send()
whr.WaitForResponse()

MsgBox, % "Without SetTimeouts`n" (A_TickCount-StartTime)/1000 "`n" whr.ResponseText


Modify ReceiveTimeout to 120 seconds:

Code: [Select all] [Download] GeSHi © Codebox Plus

startTime := A_TickCount
ToolTip, (Modify ReceiveTimeout to 120 seconds) waiting...

ComObjError(0)
whr := ComObjCreate("WinHttp.WinHttpRequest.5.1")
whr.Open("GET", "http://tmplinshi.sinaapp.com/test/timeout-test.php", true)
whr.SetTimeouts(0, 60000, 30000, 120000)
whr.Send()
whr.WaitForResponse()

MsgBox, % "Modify ReceiveTimeout to 120 seconds`n" (A_TickCount-StartTime)/1000 "`n" whr.ResponseText

The code of timeout-test.php:

After 40 seconds I get the message box with both scripts.

:shock: Without SetTimeouts, I can't wait more than 30 seconds Every time... Are you sure you wasn't running the second code twice? :|

Just retested, took just a hair over 40 seconds each time regardless of which one I was using. Something on your end?

Thanks for your testing. What I got is, the first code timeout at about 30 seconds (29.9999 or 30.xxx) each time.
Is it possible that your OS has fixed this? Windows 10? I'm using win7 x64.

Win 7 x32

Make a version where the timeout is 20 seconds, I'm kinda curious as to what'll happen.

It seems to behave as I'd expect. If I set at timeout below the timeout-test sites known timeout time (sorry, that's a lot of uses of the word time) then it errors. If I set it after that, or don't set it, it works fine. If you're getting a consistent 30 seconds, I'm guessing it's something on your end. It seems to work exactly as the documentation supports.

Thanks again gilliduck. I believe your computer is not normal... :crazy:
