Hi, I have a question about the header handling logic of mod_cache/mod_disk_cache.
With an installation running mod_disk_cache and a custom module which fiddles with Cookie and Set-Cookie headers I am running into the problem that mod_disk_cache was storing Set-Cookie headers in the cache. It is ignoring the "CacheIgnoreHeaders Set-Cookie". In mod_disk_cache's store_header() function we have this code: apr_table_t *headers_out; headers_out = ap_cache_cacheable_hdrs_out(r->pool, r->headers_out, r->server); [...] headers_out = apr_table_overlay(r->pool, headers_out, r->err_headers_out); rv = store_table(dobj->hfd, headers_out); So it copies r->headers_out to the local headers_out variable, and removes all unwanted headers. However, then r->err_headers_out gets merged into headers_out which is then stored in the cache. Is there a reason why this is done? This could lead to quite a number of headers being stored in the cache such as Set-Cookie. Which happens in my case as the custom module operates on r->err_headers_out. So a potential fix would be to merge r->headers_out and r->err_headers_out into the local headers_out variable, then filter the unwanted headers, and store the result. This seems to work, but maybe I'm missing something. ciao... -- Lars Eilebrecht l...@eilebrecht.net
