Hello All, I realized that the reason that the function doesn't do what I want is that I am using the ap_setup_client_block() call in the function, which reads client block content for POST or PUT requests.
I am attempting to read the content on a GET request. Is there an analogous function I can use? Or a simple API?

However I see a null buffer on every request. Is there a certain order that I have to execute my modules? I have tried to execute it in FIRST, MIDDLE and LAST positions. I have also tried to execute my module directly after mod_proxy. Is there some other issue with this function? I have tried to look at the mod_deflate module as an example, but I am not able to understand it in order to apply its principles here. So, if it would be possible to fix the following function to make it work, that would be greatly appreciated. static int util_read(request_rec *r, const char** rbuf) { int rc; if ((rc = ap_setup_client_block(r, REQUEST_CHUNKED_ERROR)) != OK) { return rc; } if (ap_should_client_block(r)) { char argsbuffer[HUGE_STRING_LEN]; int rsize, len_read, rpos=0; long length = r->remaining; *rbuf = apr_pcalloc(r->pool, length + 1); while ((len_read = ap_get_client_block(r, argsbuffer, sizeof(argsbuffer))) > 0) { if ((rpos + len_read) > length) { rsize = length - rpos; } else { rsize = len_read; } memcpy((char*)*rbuf + rpos, argsbuffer, rsize); rpos += rsize; } } fprintf(stderr,"Buffer: %s\n",*rbuf); return rc; } static int my_handler(request_rec* r) { char msg_content[1024] = {'\0'}; util_read(r,(const char**)&msg_content); return DECLINED; } Thanks, Pranesh -----Original Message----- From: Nick Kew [mailto:n...@apache.org] Sent: Monday, January 09, 2012 10:52 AM To: modules-dev@httpd.apache.org Subject: Re: Reading content of requests entering Apache On Mon, 9 Jan 2012 10:33:53 -0500 "Pranesh Vadhirajan" <vadhira...@teralogics.com> wrote: > Hello All, > > I would like to know how to be able to read the content of the request > that Apache receives. What you describe is called an Input Filter. There are examples in the the standard apache distro: for example, mod_deflate and mod_sed offer input filters. mod_security and mod_ironbee are third-party examples. I could also recommend the book: see http://www.apachetutor.org/ -- Nick Kew
