General :: Curl - Curl API To Configure Only The Required Protocol?

Jun 24, 2010

Is there any curl API to configure only the required protocol. If I have proper openssl installed, the installed curl will have all the protocols (like HTTP, HTTPS, FTP, File etc...) supported by default. Is there any way to allow or disallow only some of the protocol at the runtime. Say I need to support only HTTPS, FILE and I dont want to allow HTTP. Is there any way to do this?

Programming :: Sockets - P2 - P3 Http Connection Taking More Time Than The Expected?

Mar 31, 2011

Iam using socket programming in one of my problem. The scenario is like this.

=>one module is working as a socket server(process p1) is able to handle client sockets on that port.
=>one module is working as socket client (process p2) is connected to server socket and Tx/Rx data on this socket. This module has some more threads, based on received data from server socket it will connect to http on other thread and get information...
=>one more module is working as socket client (process p3) is also connected to server socket and doing some other transactions.

Here my problem is when in presence of p2, p3 http connection taking more time than the expected. If we wont start p3(means only one server-client socket) then http connection is fast enough.

Programming :: Curl And ASP Authentication - Cannot Verify Credentials

Sep 6, 2010

I've got an asp page (I can't edit) which I can access with a test user I've setup, however when I try to access to same page via curl, I get the following error:
<h1> You are not authorized to view this page </h1>

The URL you attempted to reach has an ISAPI or CGI application installed that verifies user credentials before proceeding. This application cannot verify your credentials. There's lots of other text (doubt it's relevant though).

Here's the one liner I'm using:
curl -A "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)" -u myusername:mypassword [URL]
I've done some searching but cant find anything which doesn't suggest rewriting the asp...

Programming :: Submitting Using Curl - Include Html Tags?

Jun 24, 2011

I am writing a script that is used to submit a package to testflight from my build system. In order to make the presentation as clear as possible I would like to include some basic HTML in the note section, however, using a < or > causes an error in curl. I have tried different variations of quoting and escaping but have not yet been able to find the solution.

VERSION_HEADER='<strong>Version: </strong>'


If I use VERSION_HEADER="'<strong>Version: </strong>'" then the single quotes are submitted.

If I use < or > then those are submitted but the receiving api does not decode them correctly.

Can anyone suggest a way to submit exactly: <strong>Version: </strong>

Networking :: Connection Destroy Time With Net Filter Connection Tracking?

May 13, 2011

When I have video running and the video stops, I see that the connection is destroyed in about 5 seconds, which is what I want. If, rather than stopping the video, I pull the plug, I have seen it take 350 and 380 seconds before the connection is destroyed. Why is there such a large difference in the time to destroy a video connection between stopping the video and pulling the plug on it when using net filter connection tracking? How can I shorten the time for the connection to get destroyed when pulling the plug?
