Something unusual is happening. The access log shows a url which contains "?STRING=adf" (the fourth line down). The backslashes at 80 characters are due to line-wrapping and are not a part of the actual query string 192.168.1.210 - - [15/Mar/2005:14:10:45 -0800] "GET /redirect%3Fhost%3Dh0000007\ %3Bsize%3D%3Bt%3Dhtml%3Bc%3Dff%3Btarget_id%3D0%3Bvcuser%3Dtbrannon%3Bban ner%3Da\ 0015036%3Bvcurlpreserve%3Dhttp://www.networkd.com/cgi-bin/promo/domain-\ search?STRING=adfasdf&submit=%A1Busca%21&code=P13C370S502N0B75A1D645E000 0V100&r\ egOption=%2Fen_US%2Fpurchase-it%2Fview-your-order.jhtml HTTP/1.1" 302 251 "http\ ://intra.q1.valueclick.com/stbui?banner=15036&t=html&vcuser=tbrannon" "Mozilla/\ 4.0 (compatible; MSIE 6.0; Windows NT 5.1)" However, the rewrite log shows a URL truncated just before "?STRING=adf" : 192.168.19.215 - - [15/Mar/2005:14:06:48 -0800] [b1.q1.valueclick.com/sid#81147\ b4][rid#80eb854/initial] (3) split uri=http://localhost:8981/redirect?host=h000\ 0007;size=;t=html;c=ff;target_id=0;vcuser=tbrannon;banner=a0015036;vcurl preserv\ e=http://www.networkd.com/cgi-bin/promo/domain-search -> uri=http://loc\ alhost:8981/redirect, args=host=h0000007;size=;t=html;c=ff;target_id=0;vcuser=t\ brannon;banner=a0015036;vcurlpreserve=http://www.networkd.com/cgi-bin/p\ romo/domain-search 1/ What might cause a URL to be truncated between the time the request is received and the mod_rewrite stage? 2/ What could I use to have a more verbose trace of what happens throughout the life of a request. Changing LogLevel to debug did not seem to yield much more information. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
