NPN_PostURLNotify treating my headers as data

[Rudi Sherry]

Hi all,

I am having trouble adding headers to a POST using NPN_PostURLNotify in Firefox 15.0.1. As far as I know I'm using NPN_PostURLNotify correctly, but it is putting my header in the data section of the POST.

I tried two ways: one with a memory buffer and one with a file, with the same results.

I have tried both '\n' and '\r\n' with the same results.

Firefox 14.0.1, for memory buffer, shows the same results (I didn't try the file for that).

Is there something I'm missing?

("instance" is my NPP instance).

// Use Memory Buffer
NPError err = NPERR_NO_ERROR;
static const char *sHeaders = "Custom:\tfoobar\nCookie:\tfoobar\n\nPostData\n";
NPError err = NPN_PostURLNotify( instance,
"http://host.com/home.html", NULL,
strlen(sHeaders), sHeaders, false, (void *) 1000 );


// Use file
static const char *sFilename = "C:\\Temp\\tempdata.txt<smb://Temp//tempdata.txt>";
static const char *sCustomHeader = "Custom:\tfoobar\n";
static const char *sCookieHeader = "Cookie:\tfoobar\n";
static const char *sLF = "\n";
static const char *sPostData = "PostData\n";
FILE *f = NULL;
errno_t ferr = fopen_s( &f, sFilename, "wb" );
if ( ferr == 0 && f != NULL )
{
fwrite( sCustomHeader, 1, strlen(sCustomHeader), f );
fwrite( sCookieHeader, 1, strlen(sCookieHeader), f );
fwrite( sLF, 1, strlen(sLF), f );
fwrite( sPostData, 1, strlen(sPostData), f );
fclose( f );
NPError err = NPN_PostURLNotify( instance, "http://host.com/home.html",
NULL, strlen(sFilename), sFilename, true, (void *) 1000 );
}


// Fiddler shows this for both:

I should have searched bugzilla: need to have my own Content-Length custom header as well:

https://bugzilla.mozilla.org/show_bug.cgi?id=457916

That works.
