Hello Ray,
Thanks for the update.
I tried adding below configuration in the "cas.properties" file: -
cas.httpClient.connectionTimeout=5000
cas.httpClient.asyncTimeout=5000
cas.httpClient.readTimeout=5000
cas.httpClient.truststore.psw=changeit
cas.httpClient.truststore.file="C:\Users\Administrator.IDIV-DEV1\.keystore"
where this keystore contains the certificates of ASP app but still not success. I tried putting logs in the "CasLogOff" function present in the ASP app but it is not getting hit when /cas/logout is called from a new tab.
Also in CAS traces i have seen below error. May be this can be the reason.
