Curl problem

[dpacmittal]

I made a script (I can't post the code for some reasons) that does what it intends to but when I run the same script more than one time simultaneously, it doesn't work.

It works when I did myself, but when I ran the script all at same time from browser, it didn't work. What can be the possible reasons for this?

 

I came to following causes:

1) The server doesn't accept more than 1 request from a IP.

2) The script allows only 1 connection per account. I tested this one with multiple accounts but the problem was same.

 

But then again, the script stops after login. The script logins to a remote site and fetches some data. The script successfully logs in the site and stops after that.

What may be possible reasons?

 

Thanks
