Redundant authentication

Hi, I'm coding an app to grab both statistics and performance data from a device. Since I'm using C, this involves my use of both SystemSystemInformation.cs and LocalLBVirtualServer.cs, among other files. In order to work with either of these classes as is, I have to separately pass credentials and the URL to both of them -- seemingly connecting to the same device twice, just because I want slightly different data. Does this add a lot of overhead? I want to keep pretty efficient.

 

 

Do you have any tips, if it would be better to authenticate only once, of how I could consolidate code from these two different libraries? It doesn't seem trivial to me. ...Or anything else I've failed to consider?

 

 

Thanks,

 

Brian

    I know this is a bit off topic from your post, but I was wondering if you would be able to maybe post or share your C code. I am starting to work with an f5 and would love to be able to see some examples for version 9.

     

     

    Thanks!

    As far as I know there is no way to share HTTP connection information across different classes. I wouldn't worry about it though as all each really is is a separate HTTP connection. Look at all the different HTTP connections your browser makes when hitting a website.

     

     

    Using a single interface with only one configuration has no more overhead on the BIG-IP than using two different interfaces.

     

     

    Actually within the same interface, subsequent method calls will make separate connections just as a second interface would.

    Check out the CodeShare section of this site as well as the SDK. There's a bunch of C code in there.

    Joe-

     

    Thanks a lot!

     

     

    djlos-

     

    All of my code is basically just using the sample code in the SDK in a different context. It would probably help you more just to look at that code, because it's in a general context, as opposed to my more-specific code. Check out the code located here in the SDK:

     

     

    ZIPFILE\iControl-9.2.2\sdk\samples\soap\c\microsoft\System\SystemInfo

     

     

    This is what I used as my foundation.

    Yea I was looking at some of the codeshare and the demo that you did actually for using Visual Studio. But I just was wondering if you did an updated version of that simple/sample app using the version 9 sdk.

     

     

    Thanks!
