Connect to http server / check if file exists [modified]

[ALLERSLIT]

Hello, id like to connect to a http server, preferably in a multiplatfrom working way so the code will work on linux and windows, a windows only way is fine for now aswell i guess (c/c++ only). After the connection is established i want to check if a file exists. Open for any function recommendations /papers etc. Just anything. Thanks.

A non-portable way might be to use URLDownloadToFile(). You might also check the socket API.

A portable solution would be using one of the many C++ networking libraries offering a "HTTP client". Checking if a file exists is as simple as making a HTTP request and see if something else than status code 200 is returned, strictly speaking 404 means file not found. /M

I'd suggest cURL http://curl.haxx.se/[^], or rather the libcurl bit of it. Works on Windows, Linux, FreeBSD, OS/X and Solaris and those are just the platforms I've used it on. Cheers, Ash
