Si on veut changer la version d'Apache de uWamp, il faut suivre les étapes décrites ci-dessous :

1. Downloaded the Apache 2.4 VC14 32bits from ApacheHaus. Select the 32bits apache version even if windows is 64bits)
2. Unzip the downloaded apache to UwAmp\bin directory (to obtain UwAmp\bin\apache24)
3. rename the original UwAmp\bin\apache to UwAmp\bin\apache_old
4. rename UwAmp\bin\apache24 to UwAmp\bin\apache
5. copy UwAmp\bin\apache_old\certificats to UwAmp\bin\apache\certificats
6. copy UwAmp\bin\apache_old\conf\httpd_uwamp.conf to UwAmp\bin\apache\conf\httpd_uwamp.conf
7. copy UwAmp\bin\apache_old\php.ini to UwAmp\bin\apache\php.ini
8. if it doesn't exist, create the 'sessions' directory in the UwAmp\bin\apache\ directory
9. merge UwAmp\bin\apache_old\conf\extra with UwAmp\bin\apache\conf\extra (keep the newest files, just copy the old ones to the new apache dir : httpd-ahssl.conf, httpd-deflate.conf, httpd-proxy-html.conf, httpd-vhosts.conf)

That's all! Verify by starting uWamp then open localhost and look at the apache version number. Look in the uWamp log messages window for notices or errors if any. If something went wrong just roll back to the original apache by renaming back the 2 folders:

close uWamp rename the newest UwAmp\bin\apache to UwAmp\bin\apache_new rename the original UwAmp\bin\apache_old to UwAmp\bin\apache
