Hi, Thanks for the response. As the redirector threads are started by squid, I did a strace on it. I noticed the following in the strace output in case of squid when malformed urls are getting generated :- Case 1) write(12, "1077360367.332 RELEASE -1 FFFFFF"..., 158) = 158 read(16, "GET http://java.sun.com/notfound";..., 4095) = 365 read(6, "\n\n", 8192) = 2 write(6, "\330\313(\10\334\261\22Bava.sun.com/notfound.jsp"..., 111) = 111 write(17, "GET /notfound.jsp?requrl=/css/co"..., 444) = 444 read(17, "HTTP/1.1 404 Not found\r\nServer: "..., 87380) = 781 write(16, "HTTP/1.0 404 Not Found\r\nServer: "..., 814) = 814 read(16, "", 4095) = 0 read(17, "<!-- BEGIN VNV1 MASTHEAD COMPONE"..., 87380) = 1460 read(16, "", 4095) = 0 write(16, "<!-- BEGIN VNV1 MASTHEAD COMPONE"..., 1460) = 1460 read(17, "\" \" /></td>\n<td valign=\"top\" cla"..., 87380) = 1460 read(16, "", 4095) = 0 write(16, "\" \" /></td>\n<td valign=\"top\" cla"..., 1460) = -1 EPIPE (Broken pipe) --- SIGPIPE (Broken pipe) --- write(5, "1077360368.030 693 10.10.10.1"..., 123) = 123 read(16, "", 87380) = 0 write(12, "1077360368.031 RELEASE -1 FFFFFF"..., 160) = 160 read(16, "GET http://java.sun.com/images/1";..., 4095) = 315 read(6, "http://localhost:8080/contentfil";..., 8192) = 178 write(6, "\3408>\10://java.sun.com/images/1x1.g"..., 61) = 61 write(17, "GET /contentfilter/login1.jsp?ur"..., 511) = 511 read(18, "GET http://216.239.57.99/search?";..., 4095) = 385 read(6, "http://localhost:8080/contentfil";..., 8192) = 128 write(6, "http://216.239.57.99/search?clie";..., 182) = 182 write(19, "GET /contentfilter/login1.jsp?ur"..., 440) = 440 read(17, "HTTP/1.1 200 OK\r\nDate: Sat, 21 F"..., 87380) = 3879 write(16, "HTTP/1.0 200 OK\r\nDate: Sat, 21 F"..., 3912) = 3912 read(17, " <td> \n "..., 87380) = 1349 write(16, " <td> \n "..., 1349) = 1349 read(16, 0x83d89a8, 4095) = -1 ECONNRESET (Connection reset by peer)
Case 2) write(12, "1077360407.457 RELEASE -1 FFFFFF"..., 174) = 174 read(16, "GET http://localhost:8080/conten";..., 4095) = 348 read(6, "http://localhost:8080/contentfil";..., 8192) = 141 write(6, "\334\261\22B\334\261\22Bocalhost:8080/contentfil"..., 78) = 78 write(17, "GET /contentfilter/login1.jsp?ur"..., 489) = 489 read(17, "HTTP/1.1 200 OK\r\nDate: Sat, 21 F"..., 87380) = 3746 write(16, "HTTP/1.0 200 OK\r\nDate: Sat, 21 F"..., 3779) = 3779 read(17, " <td> \n "..., 87380) = 1349 write(16, " <td> \n "..., 1349) = 1349 read(17, "", 87380) = 0 write(5, "1077360407.540 44 10.10.10.1"..., 138) = 138 read(16, 0xbffe7e90, 87380) = -1 EAGAIN (Resource temporarily unavailable) write(12, "1077360407.540 RELEASE -1 FFFFFF"..., 178) = 178 read(16, "GET http://localhost:8080/conten";..., 4095) = 347 read(6, "http://localhost:8080/contentfil";..., 8192) = 145 write(6, "\350g>\10\334\261\22Bocalhost:8080/contentfil"..., 77) = 77 write(17, "GET /contentfilter/login1.jsp?ur"..., 494) = 494 read(17, "HTTP/1.1 200 OK\r\nDate: Sat, 21 F"..., 87380) = 3746 write(16, "HTTP/1.0 200 OK\r\nDate: Sat, 21 F"..., 3779) = 3779 read(17, " <td> \n "..., 87380) = 1349 write(16, " <td> \n "..., 1349) = 1349 read(16, 0x83cc5a8, 4095) = -1 ECONNRESET (Connection reset by peer) From this I observe that squid is reading twice and writing twice. Why does this happen? Is it because the client is writing to it twice? Secondly, I did an strace on the redirector program but am not getting any output - plz tell me how to do it.
