Re: using ajp (isapi_redirector2.dll) without tomcat on IIS (is_inited =0 in HttpExtensionProc)

[James Chang <jc...@hotmail.com>]

Hi,

    Here is more information I got.  It looks like what happened is, the
socket open and data sending is done in HttpExtensionProc,
However the static int is_inited is always 0 when that function is called.
However is_inited is been set to 1 upon dll initialization by another
thread,
and when HttpFilterProc is called by IIS, the is_inited is 1.

    Almost looks like the 2 functions (filterProc and ExtensionProc) is been
called from 2 different stack frame from IIS, but when the address
of the variable is the same (XP virtual memory trick?).

    I am using windows XP Pro latest patch (as of jan 27, 2003) and IIS
5.01.
    Anybody got any ideas?

    Thanks

I have downloaded apache binary dist and the ajp connector source, and
builded the IIS redirector (It was rather strange that apr.h is in apache
binary dist but not in the apache source release).

What I found with debug messages is,  HttpFilterProc() is called with I
request http://localhost/examples/xxxxx, which means the dll is installed
correctly and the configuration files are correct (mappings and etc).
However there is no line of code in HttpFilterProc() that actually calls
anything to open the socket and send data.  I checked several possible
functions to see if they are the ones who send data, but all turn out to be
some string manipulation functions.

Could someone tell me which function call in HttpFilterProc actaully result
in open socket to 8009 port?

Thanks

Help: Why HttpFilterProc and HttpExtensionsProc on 2 different process in isapi_redirector2.dll?

[James Chang <jc...@hotmail.com>]

Hi,

       System: windows XP pro, IIS 5.1.   isapi_redirector2.dll is not doing
its job.
        isapi_redirector2.dll from:
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk2/release/v2.0.
2/bin/win32/

        What happened is, when IIS starts up, it calls dll_Main for all its
threads and calls GetVersion() 1 time, in the function isapi_redirector2.dll
initializes everything and set is_inited to TRUE.  All those happens in one
process (the same process IIS calls HttpFilterProc).

    However when the match is found and the redirector tries to call Tomcat,
IIS calls HttpExtensionProc from ANOTHER process, basically in this process
nothing is initialized (the process id get by GetCurrentProcessId() is
different from the first process).

    Anyone got any ideas?

    Thanks
