Authentication Loop through IIS VS

 

Information

 

Summary:

An authentication loop is occurring when connecting through an IIS VS with multiple SubVSs.

Environment:

Product: LoadMaster

Version: Any

Platform: Any

Application: IIS

Question/Problem Description:

Our servers are running several different IIS sites separated by host headers. I tried to set up a SubVS for each site in the Kemp. I am getting a 'too many redirects' error when a site goes to do user authentication.

Steps to Reproduce:
  • Create a VS with SubVSs
  • Don't apply Content Switching rules to the SubVSs.
Error Message: Too many redirects
Defect Number:  
Enhancement Number:  
Cause: When an application generates multiple connections, the LoadMaster will load balance among the SubVSs, if no Content Switching Rules are applied.
Resolution:
  • Create a Content Rule for the content you'd like to match under Rules & Checking > Content Rules > Add New.
  • Once created, navigate to your desired Virtual Service > Advanced Properties > enable Content Switching > expand SubVSs > click on the "None" button in the Rules column > apply your desired rule for the SubVS in question.
Workaround:
