curl error : 52 - help
Date: Mon, 2 Oct 2006 10:43:24 -0700 (PDT)
Hi,
Please provide any help on below problem.
Problem :
-----------
Please find attached the log trace for the steps through "Browser" and same through "PHP+libcurl" scripts and also the "libcurl script" for this.
Below error occurs during the php-libcurl scripts execution.I am able to login to the website perform all following actions ("GET"/"POST")until the below step where i get this error.
Details of the Error:
======================
cURL error number :52
cURL error:error Empty reply from server* Closing connection #0 { which means, "Nothing was returned from the server "}
As seen in the attached trace :-
1) The Request is same as Browser Request
2) There is a correct redirection by server to “GET” "https://abc.def.ghi/ABC/Upload.asp?pqr=2"
But instead of “Getting https://abc.def.ghi/ABC/Upload.asp?pqr=2%94 there is error as mentioned above
a)Is it because web browsers always work slower than the curl?
b)Is it that test.php takes longer time to run and the curl process returns before it finishes?
If so, how can we delay the curl execution-time?
c)Is it a problem at server - end? unfortunately, i donot have access to the server logs.
Please provide any help / suggestion if someone had this problem.
Thanks in advance,
LP
