Https URL with User Id and password

Hi Experts ,

I have a requirement where I have to share my WSDL URL along with the user name and password , so if we call the URL it does not give the pop up of entering the username and password .

Sample URL :

https://******:*****/dir/wsdl?senderParty=&senderService=******&receiverParty=&receiverService=&interface=********&interfaceNamespace=****&UserName=***&password=*****

I have tried this combination , but even after this , whenever i am calling the URL its is showing a pop up to enter credentials ?

Any pointer will be helpful

I have tried in channel both wiith Https with and without client authentication .
