How I can decode WebSphere Portal url?
For example this url: /wps/portal/!ut/p/c5/dY7LdoIwAAW_hS9ICEnEZSBaKBSKkUfZcAKtKRYMKo-2X197XHtnObO4oAQ3TnJulRxbfZIdKEBJK2wn24y
Try the following:
/wps/poc?uri=state:URL&mode=download
where URL is your original URL for example:
/wps/poc?uri=state:/wps/portal/!ut/p/c5/dY7LdoIwAAW_hS9ICEnEZSBaKBSKkUfZcAKtKRYMKo-2X197XHtnObO4oAQ3TnJulRxbfZIdKEBJK2wn24ylATUpWUNfhLt9anHTJgg8g1J1ur6VOX_T31wzxRk_4NHZobEvzs5Vu6o3942nbJRTEpNl-UHmoK5JGlfvpOHThtV04ksmNlac5oHuz-HWb4QMcTQHr11SE3xZTUPdz9GvKwkTRfsydMdJHrQTd-vPizIMkP8_p5X7xDy8CiGMUQYhiohIYCos6Ft3Dx-MQRB5uv8Aw1cNj5gZfxocKIs!/dl3/d3/L2dJQSEvUUt3QS9ZQnZ3LzZfNDhRRlZBVUs2UEZMRDBJU1RDTEZIRTEwTDM!/&mode=download
I do not have a running portal to check that but according to my notes it should work.
