Hello, I've been trying to find a solution to a problem that mod_cache has with handling Etag's properly. I'm working with Apache 2.0.51. Below is a diff to ./server/util_script.c that seems to fix the problem...
564a565,567 > else if (!strcasecmp(w, "ETag")) { > apr_table_set(r->headers_out, w, l); > } My concern is that this might have some other negative effect on something. Does anyone see any problem with adding Etag handling to the ap_scan_script_header_err_core() function? The reasoning here is that mod_cache calls this function to populate the r->headers_out table from the ".header" file in the cache. But the function sticks the Etag value in the r->err_headers_out table. Then, mod_cache later calls ap_meets_conditions() which expects to find an Etag value in r->headers_out. The above diff seems to be the cleanest way to solve the problem, but I wanted to check and see if it causes any other problems. Thanks, Mike C.
