Hi,
I am debugging on httpd 2.0.45. In core_output_filter() (in source file core.c),
if I return HTTP_SERVICE_UNAVAILABLE,
WebDAV server answers "HTTP/1.1 200 OK" with an error page.
I try to handle an error case in core_output_filter():
(See comments at "if (rv == 89)" ):
static apr_status_t core_output_filter(
ap_filter_t *f,
apr_bucket_brigade *b)
{
.................
if (rv != APR_SUCCESS) {
ap_log_error(APLOG_MARK, APLOG_INFO, rv, c->base_server,
"core_output_filter: writing data to the network");
/**
* I get "Unsupported file system operation" (error code 89), then I try
* to return HTTP_SERVICE_UNAVAILABLE. But when I reach here
* in WebDAV server, WebDAV server answers "HTTP/1.1 200 OK"
* with an error page "Error 503". See the full answer of my test from WebDAV
* server below in this mail. It is worth to mention that if I don't handle
* it here, I get a blank page from WebDAV server.
*/
if (rv == 89)
return HTTP_SERVICE_UNAVAILABLE; // Added
by me
if (more)
apr_brigade_destroy(more);

}
