Thanks for the report.
We'll vendor the bugfix once it has landed in cachecontrol :)

[grokcode]

@xavfernandez this just landed in cachecontrol master. Is there anything I can do here to help vendor the bugfix?

[dstufft]

@grokcode Um, well once @ionrock cuts a new release of CacheControl we'll pull it in automatically on the next release of pip.

[grokcode]

Thanks for the update @dstufft.

[ionrock]

I just released 0.12.1.

[xavfernandez]

Closed by #4342. A change log is still missing though :)

NameError: global name 'get_page' is not defined

am getting the following error what to do.... please help itz urgent

[pradyunsg]

@digitalstem I imagine you'd want to seek inputs from other channels such as python-list or python-tutor mailing lists, #python on Freenode (IRC) or StackOverflow -- they would be better channels to get support for the issue you're facing.
