Persist an HTTP session across all SOAP calls
In circumstances when a SOAP client makes many calls in a short amount of time, you may want to re-use a single HTTP session for all SOAP calls.
Each SOAP call creates a new user session that persists until it expires. To create a single user session and re-use it for all inbound SOAP calls, develop your SOAP client following these guidelines:
- Use a module like HTTP::Cookies to create a "cookie jar."
- Save the cookies returned by ServiceNow after each request (handled automatically by HTTP::Cookies).
- Re-send the cookies in the cookie jar with each subsequent request.
Note: If you have enabled the session rotation high security setting, it will immediately invalidate the JSESSIONID returned from the server with the first response header. The second response includes a new JSESSIONID.
In perl, you can automatically save and send cookies with the following code:
use HTTP::Cookies;
#we want to store and re-send cookies
my $cookies = HTTP::Cookies->new(ignore_discard => 1);
my $soap = SOAP::Lite
-> proxy('http://localhost:8080/glide/ecc_queue.do?SOAP');
#Set the cookie jar
$soap->transport->cookie_jar($cookies);
