There's a similar error message to yours in 2.4, but not in 2.2: /* We didn't get the magic bytes. */ if (len != 10 || deflate_hdr[0] != deflate_magic[0] || deflate_hdr[1] != deflate_magic[1]) { ap_log_rerror(APLOG_MARK, APLOG_WARNING, 0, r, APLOGNO(01387) "Zlib: Invalid header"); If that check is incorrect, something needs fixing. Bug me if I don't get round to checking it myself! Is it possible you have some other filter that's corrupting the byte stream ahead of mod_deflate? Or some other encoding that's not correctly handled? -- Nick Kew --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
