Browser faster than protocol?

[batori]

Hi,

I have recently tried various ways (even custom chillkat reference) of upload a file to a server via HTTP with POST command ... but nothing seems to be fast as a normal webbrowser (mozilla, chrome) upload speed?


Have you experienced the same thing? Why is that?


Cheers!

They could be dividing the file into multiple chunks, opening a series of sessions, and sending different chunks out different sessions. Whether or not this happens, I have no idea.

as a normal webbrowser (mozilla, chrome) upload speed?

There is, of course, no such thing as a normal browser upload. All the processing is done either within the webpage scripting or on its server and, as Shaggy said, that could involve any number of special techniques to speed the process. Either way it will be unique to the site.

I've checked with Fiddler...and what i've seen is only one request being made when uploading through a webbrowser interface (mozilla, chrome) ... but upload speed is darn fast!

I've simulated the exact same request within vbnet and the speed is just waaay slower....

EDIT:

Maybe it's about chunksize or something ....

Content-type: multipart/form-data, boundary=xxxx..... ?

bump?

How are you measuring the speed of the different methods? How big is the file? Is there a reason you are using HTTP POST?

[batori]

adding handlers...and when everything is done i check my uploaded files...which correspond to the progress of the app...

why am i using http...well im just simulating what i've got from fiddler when "intercepting" packets...and the same request is being made from browsers, therefore i incorporated in the app...but the upload speed is way way slower than the browser uploading speed (chrome,ecc)
