Thread: Timing HTTP GET requests

I have a need to time the various GET requests in viewing a web page.

Each time I "get" a web page, it involves many GET requests with each one returning a response code.

One web page may have multiple GET requests for the CSS, for each of the graphics files, etc.

I need to count and time each GET request.

I've looked at cURL library and looked deeply into sockets, but I can't seem to find out how to find each GET request. Then I could add a timer.

Can anyone point me in the right direction?

Please help.

Thank you in advance.

If you can do it in a web browser, then Firefox and Firebug will give you this info.

I need to do this in a C program

I see the original GET request:

GET / HTTP/1.1\r\n

Then multiple other GET requests:

GET /Files/styles.css HTTP/1.1\r\n
GET /Files/functions.js HTTP/1.1\r\n
GET /Images/shadow_Left.gif HTTP/1.1\r\n

...

If I use libcurl or sockets, I can create the first GET (GET / HTTP/1.1\r\n) but I never create the other GETs.

I want to see each of the GETs being sent so I can set a timer to see how long each GET takes.

Any ideas?

Wireshark (formally known as Ethereal)?

Yes I can use Wireshark. But I want these numbers from a C program. I'd like the same stats as Wireshark shows, but I can't figure out how to get them.

I'd like the time it takes to connect, time to first byte and time for download.

I thought about getting a list of all the files from the web page and doing them one at a time, but I see that Wireshark and HttpWatch Professional show the individual times like I would like, but they don't do it independently - as far as I can tell.

Anyone else have any ideas?

Sure. Why not just poll your most accurate way of telling time on your computer prior to beginning your HTTP transfer and poll it again after you have completed all transfers. Getting stuff off of a web-page is not the most difficult network programming. So are you having trouble parsing HTML or are you just plain not knowing how to do time stamps?

That's a good idea. For windows, you could compare GetTickCount before and after.
