The cppreference.com fails to cache #115

Closed edgar444 closed 3 years ago

edgar444 commented 3 years ago

Version of cppman:

$ cppman -v |& head -1
/usr/bin/cppman Ver 0.4.9
$ qfile -vS $(which cppman)
app-doc/cppman-0.4.9:0: /usr/bin/cppman

Caching fails when switched to different source:

$ cppman --source=cppreference.com
Source set to `cppreference.com'.
$ cppman -c
By default, cppman fetches pages on-the-fly if corresponding page is not found in the cache. The "cache-all" option is only useful if you want to view man pages offline. Caching all contents will take several minutes, do you want to continue [y/N]? y

The server tries to redirect to en.cppreference.com, which is the cause of the issue:
