Hi, We set a custom variable in HTTP header. We want to log the custom variable in apache access logs. LogFormat "%h %l %u %t \"%r\" %>s %b \"%{XYZ}i\"" combined CustomLog logDir/access_log combined We tried logging whole header info., this is coming as empty string? LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Header}i\"" combined CustomLog logDir/access_log combined Could you please help, how to read a custom header variable or whole header? Thanks Srini
