| Subject: | [PATCH] url() handle script_name as regex |
I have this url:
https://xxxx.redhat.com/satconfig/cgi-bin/fetch_netsaintid.cgi?ssk=xxxxxx&publickey=ssh-dss%20AAAAXXXXXXXXXXXXXXXDi0Qp8%2Bxvt69c3%2FaCiNA5oraeyCRskfsubZ62qSWg4F4LAPxF0jqzDuGM0X8fvnQnDkddK28%2B41BO6Om5R%2Fp%2F%2Fr0Rs9M9yXrsvm%2BomGIgWEOWqxnEL3qtL64Kpf2%2BMX%2Fh0h7LIDeF5z0Bovr2tvT3zcALdFlhj83uJqcWxOPAAAAFQCunhs9qUE5vSAIUDJRLjy0QFmr2QAAAIEAqizqsrAJHiftNrEgjx%2B%2Bwpa9KJg3BBDLWhR%2F8e65UVPhlJQOYrF7ihsWn8zfr1sH%2BXoxzWVJh%2BfaIRkLahAIgh9fP2kd5ZxUViM6Qovgkvp5UKo4Uwg8k8FEJNduu4A4GvvXDFd8nMJVrNDFVdLuwpnPBVSVqdBvt3ATdAcQhYYAAACACwjh7j1kEprwPB29fbtsRpkMLB6M91svTa%2FGKkUhScYCwUd%2Fr%2F3FaT85C6Tb8MySHHk2xZg4EMLNZla0ldy%2FnxWJcBaPd67ooB5TvPO61iPTfuULZbtBCEaTlCp0yYLncX75Oaa2PxvIJD4GvOewu7GdpcFO%2BLblz0QpFD2g6os%3D%20root%40sat4-510%2Eenglab%2Ebrq%2Eredhat%2Ecom%0A
and it contains two plus, so I got this error:
