Hi squid developers,
I want to report 1-2 small bugs and corrections at squid icap client interface that are relative with keeped alive requests to an icap server. I am using a (corrected) squid-icap named squid-2.5.STABLE5-icap-6-pre1. but as I seen this bugs exists and in squid-icap-2.5-200405131634 icap enabled squid.
1)when icapReadReply3 called after a response request with null-body
(e.g when the content of a web page not changed ...)
then enters the block "if (EBIT_TEST(i..., ENTRY_ABORTED)){".
Squid icap-client has request keeped alive connection and
now the connection not closed. This behaviour can cause a lot of open connection to an icap server until connections expired.
An addition of comm_close(fd) in this block can solve the problem.
Moreover if think there is no need for the connection to be closed
in this phase and can keeped alive. So the entire block :
if (EBIT_TEST(i..., ENTRY_ABORTED)){
...........
}
in function icapReadReply3 can removed.2) In file icap_reqmod.c in function icapSendReqMod
when compute the position of entities for
"Encapsulated:" header squid does not include crlf (2 bytes) in possition computation.
This fields are the possition in the header not the size of the header.
I propose to
a) add a "crlf" at the end of "icap->request->header"
before Encapsulated header computation
eg "memBufAppend(&mb_hdr, crlf, 2);" at line 613
and
b) remove the "memBufAppend(&mb, crlf, 2);" line 637 that adds the crlf at the end of
entire buffer.
Regards, Christos
