socket read on a keep alive request waits until connection timeout - Web Development Discussion Boards

For asp.net, I don't see a problem with that.

if it's really optimized managed code, it should run really fast.

What does it do?

i thought cs is the extension of C# file..............................

I wish I could believe there is an after life.

Well yah it is, but the OP posted his concern in the Web Development forum, instead of the asp.net forum, so I did not want to assume anything here at this point.

The Code for sigle file can be subdivided into many files for easy execute by following particular Structure.

It's been done already. I suggest you take a look at the way Google did it.

Your answer is not fully clear to me. Would you please elaborate a little bit more.

How to know whether the server has no data while reading the response of a request which is keep alive because the socket read function waits for the server to send data if we have made a request with keep alive option.

I am writing a socket program to fetch a webpage.

My request header has no connection close header so by default the connection is keep alive.

I open a connection, send the request header using socket_write and getting using a while loop to receive data
if it is a Connection Close request the everything works well.

if it is keep alive and after i have read the content the socket_read function is still waiting for data which causes the code to hand in there.

Here how do we know whether the server has completed sending the resource though it is keep alive...

i have a work around like checking the content-length response header to know how much data is received and accordingly i can stop reading

or

if response header has transfer-encoding as chunked then i can write more code to find the end of the response

yet without the above two workarounds how to check whether the socket_recv is still waiting for data?

Besides, i was thinking that since we are setting the read buffer length (like 1024 in this code) and the socket_recv is returning the no of bytes read and if the bytes read is less than 1024 then i can assume that the next read will not return anything and by this time i can quit the while loop.... BUT http server sends different length response so my logic will not work.

Here is my request header and the while loop in which i receive date from the server

//i have commented the connection close header so that by default it will be keep alive

PHP

$o = 'GET /search?hl=en&q='.$query.'&start='.$start.' HTTP/1.1'."\r\n";
$o.= 'Host: www.google.co.in'."\r\n";
$o.= 'User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0'."\r\n";
//$o.= 'Connection: close'."\r\n";
$o.= "\r\n";

//writing $o to the socket resource

//receiving the response

do
{
    $bytes = socket_recv($f, $tbuf, 1024, 0x40);

    if($bytes === false)
              die("\r\nUnable to read headers - ".socket_strerror(socket_last_error()));

    echo "\r\n".$bytes;

    if(!$bytes)break;

    $buf.= $tbuf;
}while(1);

In the above code after i have received the complete html of a webpage the control is in the line where i am reading the response. Which i assume the code is still waiting for data from the server.

Suggestions, comments and advice's are welcome.

Hello guys, I need to use Google image with my own program. When I save the WWW.image.google.com I am not able to see the camera Icon beside the search button. I need this camera icon to click on it automatically.
can anyone tell me what is the nature of this camera icon!? is it a button or just a clickable icon!?
Thanks and regards

To confirm and see what exactly it was, I did a ViewSource of the page.

I found it's a a-href link wrapped over a span that has image as a background. A-Href link triggers a JavaScript method.
