i have a problem in my app that i cant resolve

first of all my app:

nodejs 0.8.14 express 3.1 passport-local 0.1

the problem is when i login in passport session the client request the page two times...

i discover that because i put a request var in the url

this in my router

exports.index=function(req,res)
{
    console.log('success: '+req.url);
    var sesion_usuario=validate(req.params.code_user);//if not valid return null
    if(sesion_usuario){
        res.render('logged',{title:'Hello'+sesion_usuario})

this in my browser

http://localhost:8000/YOGE7419

this in my app

app.get('/:code_user',routes.index);

and this is what im receiving in my prompt

success: /YOGE7419
success: /YOGE7419
DEBUG: validate error: maxlength not match

and the url transform in this

http://localhost:8000/YOGE7419#sthash.zp1bOY2d.dpbs

why is that??? whats happening between first and second request?? tnx

• 2 If you make request with browser, than second request may be init by brwoser for getting /favicon.ico – Eugene Commented May 7, 2013 at 15:42
• i mit favicon and still have a second request – andrescabana86 Commented May 7, 2013 at 15:44
• Do you mean you get double requests when your browser visits the url? console.log('success', req.url) will show you which url is doing the request. If it's a request password makes then you can ignore this ment. – Pickels Commented May 7, 2013 at 17:00
• @Pickels req.url == /YOGE7419 prompt print success: /YOGE7419 success: /YOGE7419 – andrescabana86 Commented May 7, 2013 at 17:18
• do you think its a request password?? – andrescabana86 Commented May 7, 2013 at 17:20

If express redirects the browser then the browser will send a repeated request (in my experience it was after 5 seconds) if the redirection has not pleted.

By adding a timeout to the redirection's request I was able to avoid the duplicate request:

app.get('/path2', function( req, res ) {
    req.connection.setTimeout( 1000 * 60 * 10 ); // ten minutes
    console.log('path2');
});

For detailed discussion read here at GitHub Link.

The first request is automatically made by the browser, which requests favicon.ico, and of course, the second request is for the URL (Your URl).
