Synonyms: ls: path and http path for project

Hello, all.

Can somebody help me to do "bzr branch lp:gcc-linaro/4.8 linaro-4.8" through http protocol? I tried to use "bzr branch http://bazaar.launchpad.net/~linaro-toolchain-dev/gcc-linaro/4.8 linaro-4.8", but I am not sure that these are synonyms. Unfortunately, I can't use ssh to 20 port.

And one more question - is it possible to push through http? If yes, how have I change "bzr push lp:~YOUR_LAUNCHPAD_ID" command?

Thank you in advance!
