Thank you for your reply. I m using HTTP Basic authentication in my application. And i have one more doubt with Curl + Single sign on, ``` Now i use username & password for all commands(Like ``` POST,PUT,DELETE,GET) to create,update,delete and read my data. ``` Is it possible to maintain the username and password until i ``` logout from cURL ---

I suppose that would depend on how the authentication is handled in the [asp.net](http://asp.net) application. Is it HTML form based, HTTP Basic Authentication, or something else? > I’m using [asp.net](http://asp.net) application and i access this from cURL .Now i want to > know,how to use single sign on in cURL. I assume from this that the [asp.net](http://asp.net) application is not handling Cross Site Request Forgery (CSRF) protection. Is that correct? You say you are accessing the [asp.net](http://asp.net) application from cURL. Does that mean you are successfully authenticating with the [asp.net](http://asp.net) application and you want keep track of the state? If so then you need to get cURL to manage the session cookies from the [asp.net](http://asp.net) application (assuming the [asp.net](http://asp.net) application is managing sessions with cookies). See the curl man page and look for --cookie-jar option. cURL also support HTTP Basic Authentication and HTTPS, so if the [asp.net](http://asp.net) application supports this authentication method then you just need to send it the username and password in the URL. [https://user:removed\_email\_address@domain.invalid/login.asp](https://user:removed_email_address@domain.invalid/login.asp). And don’t forget to use a cookie jar for managing the application’s session cookies. This is the best answer I can give with the information you have provided. Maybe a more detailed explanation of what you’re actually trying to do would help. venu gopal wrote: > hi, > > I’m using [asp.net](http://asp.net) application and i access this from cURL .Now i want to > know,how to use single sign on in cURL. > > Reply as soon as possible
