mod_proxy_connect.so: The specified module could not be found.
Today I wanted to update the Apache configuration in our DMZ to enable Git over SSH over SSL (another story) but while deploying the changes from my workstation to the server, Apache threw the error
Cannot load modules/mod_proxy_connect.so into server: The specified module could not be found.
As always procmon.exe was my friend and showed that mod_proxy_connect.so was referencing the msvcr100.dll which was not existent on the server
I fixed the error by copying msvcr100.dll from my %WINDIR%\SysWOW64 to the SysWOW64 directory of the server (both are x64 machines).
