Dear All,I'm using mod_ext_filter to convert SVG files to PNG on the fly. It looks something like this:
ExtFilterDefine render_svg_filter mode=output \ intype=image/svg+xml outtype=image/png \ cmd="/usr/local/bin/rsvg_filter.sh" where rsvg_filter is something like: #!/bin/sh tmpinfile="/tmp/rsvg.$$.dt" tmpoutfile="/tmp/rsvg.$$.png" cat > $tmpinfile rsvg $tmpinfile $tmpoutfile cat $tmpoutfile rm $tmpoutfile $tmpinfile This works well.Unfortunately, it looks as if the PNGs that this generates are not being cached by the browser. Presumably the browser is sending an if-modified-since header; I'd like to compare the if-modified-since date with the timestamp on the .svg file, and return a 304 not modified response if nothing has changed.
(I'm not sure how this interacts with Etags.) Is there a way to do this? Thanks for any ideas. --Phil. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
