ICAP redirection

We have a web application that authorized users to upload any kind of files.

 

Would it be possible to redirect those uploaded files to an ICAP server for virus check.

 

Is it possible to do that with irules or BigIP will support ICAP API in future release.

 

Thanks

  • I'd like to revive this question. I'd be interested in knowing if this can be done as well.
  • I've heard vague rumors about F5 providing local ICAP validation in an upcoming version. You can check with your F5 salesperson for more information on this.

     

     

    With a 4Mb limit on TCL variables, I don't think it's feasible to do this now in an iRule.

    All,

     

     

    Just seen this in "BIG-IP Application Security Manager version 10.2.0 Release notes", under "New Features":

     

     

    Anti-virus scanning

     

     

    With this version you can configure the Application Security Manager to act as an Internet Content Adaptation Protocol (ICAP) client. The system asks an external ICAP server to check HTTP file uploads for viruses before releasing the content to the web-server. To configure antivirus protection, from the Configuration utility, navigate to Application Security » Options » Anti-Virus Protection.

     

     

    If the system detects a virus in an incoming request, the system issues the violation Virus Detected, and logs or blocks the illegal request, depending on how you have configured the settings of this violation on the Policy Blocking Settings screen.

     

     

    We added an advanced configuration parameter, Virus header name, which is the name of the response header that the ICAP server returns when it detects a virus. The parameter’s default value is X-Virus-Name, which is McAfee’s default response header. If you are using a different ICAP server, change this parameter’s value to the appropriate value used by that ICAP server. This parameter is found on the Advanced Configuration screen (from the Configuration utility, navigate to Application Security » Options » Advanced Configuration).

  • Hi Mayur,

     

     

    What is FTP over HTTP? This isn't an implementation I'm familiar with. Do you mean FTP encapsulated somehow in HTTP? Or are you just using FTP on port 80?
