Your URL is incorrect and cannot parse by the web server.
What is (S(4wuduaje2xivjefwffjv5bgq))? is this mandatory to pass?

Member 11479116 27-Aug-15 8:42am

when I write <sessionstate mode="InProc" cookieless="true" timeout="525600"> in web config it will create (S(4wuduaje2xivjefwffjv5bgq)) this url also. for set session state.

I try all methods above but do not get solution.

Is there any solution for that ?

replace special characters with their encode value
like
' ' with '%20',

'&'with '%26
in your query string.
