  • Why is the ‘Last-Modified’ header unset for a variety of headers?

    GTMetrix complains that there is no Last-Modified header for SVG, when I looked into it, it appeared that it is being removed by W3 Total Cache on purpose. I couldn’t find any settings controlling this setting or why it’s being unset to begin with. Where is this controlled and why is it being removed?

    <FilesMatch “\.(bmp|class|doc|docx|eot|exe|ico|webp|json|mdb|mpp|otf|_otf|odb|odc|odf|odg|odp|ods|odt|ogg|pdf|pot|pps|ppt|pptx|svg|svgz|swf|tif|tiff|ttf|ttc|_ttf|wav|wri|woff|woff2|xla|xls|xlsx|xlt|xlw|BMP|CLASS|DOC|DOCX|EOT|EXE|ICO|WEBP|JSON|MDB|MPP|OTF|_OTF|ODB|ODC|ODF|ODG|ODP|ODS|ODT|OGG|PDF|POT|PPS|PPT|PPTX|SVG|SVGZ|SWF|TIF|TIFF|TTF|TTC|_TTF|WAV|WRI|WOFF|WOFF2|XLA|XLS|XLSX|XLT|XLW)$”>
    <IfModule mod_headers.c>
    Header unset Last-Modified
    </IfModule>
    </FilesMatch>
