Hi, I work actually on a framework to manage a Proxmox server. The Proxmox solution is based on a strange REST API⦠:-( To get informations about an user, I must send a string with the login and the authentication domain. The two values are separated by a character @. For example: GET /api2/extjs/access/users/auverlot@LIFL My first problem with Zinc is that the client find the character @ and the client think that this is an URL with authentication. I tried to use an encoding string with %40 but Proxmox don't find the user. The solution must be to modify the method ZnUrl>>#parseAuthority:from:to: to do a better detection of authentication pattern: parseAuthority: string from: start to: stop | index | index := string indexOf: $@ startingAt: start. (index > 0 and: [ (string indexOf: $: startingAt: start) < index and: [ index < (string indexOf: $/ startingAt: start) ] ]) ifTrue: [ self parseUserInfo: (ReadStream on: string from: start to: index - 1). self parseHostPort: (ReadStream on: string from: index 1 to: stop ) ] ifFalse: [ self parseHostPort: (ReadStream on: string from: start to: stop ) ] But, it's not the end of the road :-( Because in the next steps, Zinc encodes the character @ in the url. How to disabled the automatic encoding and using special characters in the url ? Thanks for your help. Best regards Olivier ;-)
