[twsocket] HTTP server...

2012-07-21 Thread zayin 
Hello,

A user will be on a page. He will click a button and I will receive a URL
with some parameters. All good.

Now, I do not have a page to show him. The URL is only for passing in the
parameters. The URL for the page passing the parameters and the current page
are not the same. The URL for passing in the parameters is fixed. The URL
for the button's 'host' page is not fixed.

I want the current page in the browser to stay the same. The one with the
button.

I can answer with a redirection to the current page (the button host page).
Works but not the smoothest operation.

I was wondering if there is a better solution. Some answer code that tells
the browser the data was received but not to change page or to reload the
button host page.

Cheers,

Mark

This bug should be fixed in current SVN repo or next daily/nightly
download.

[twsocket] Simple Get HTML from URL

2012-07-21 Thread Miguel Enguiça 
Hi,

I need to get the HTML content from a URL list. I don't want to spend more than 
10 seconds on each URL either if the remote server is down or a read timeout 
occurs. I've tried with:

function GetUrlContentUTF8ICS(const Url: string):UTF8String;
var
lData: TStringStream;
httpcli1 : THTTPCli;
begin
  Result:= '';
  lData :=  TStringStream.Create();
  httpcli1:= THTTPCli.Create(nil);
  httpcli1.Timeout:= 1;
  //
  httpcli1.RcvdStream := lData;
  httpcli1.URL:= url;
  try
httpcli1.get;
Result:= lData.DataString;
  except
Exit;
  end;
  lData.Free;
  httpcli1.Free;
end;

But the timeout doesn't occur and it gets hanged in slow or offline websites. 
Am I missing something. Is it needed to implement a Timer based solution for 
this?

Thanks,
Miguel
