How to Create a dynamic basepath

[Anon Anon]

Hi

 

We have multiple HTTP Virtual services to be deployed on same port. The basepath of the virtual services has a parameter (ex SessionID)  which can be dynamic.

 

Ex: Basepath of service A :  a/b/123/c

Basepath of Service B  a/b/123/d

 

Say ,Here 123 is sessionId and it can be any random value in runtime

 

How can we implement this feature in CA DevTest?

Dynamic URL parameters are fully supported if you choose the REST data protocol handler during virtual service generation. If it's not a REST service but it still uses that type of mechanism, it might be best to delete the basepath during generation and deal with the changing URL yourself in a scriptable or a custom DPH.

Hi Rick,

 

Thanks for your inputs.

 

Our requirement is to handle request before it comes to DPH. As we have more than one VS (VSM) , so based on endpoint/ basepath it should decide which VS should be called.

 

As in our case  we have 2 VSMs Service_A and Service_B

 

Basepath of service_A :  a/b/123/c

Basepath of Service_B  a/b/123/d

 

So if endpoint is a/b/123/c , request should go to Service_A and

if endpoint is a/b/123/d , request should got to Service_B

 

But as here basepath is having session ID parameter which is dynamic, I am not able to implement it in Listen step of VSM

Hi Ekta,

Is there a mandate in your scenario to mantain multiple VSM? If not I would think of having multiple VSI with single VSM. And use the scriptableDPH to decide which VSI to be called.

Thanks,

Hi Udhaya,

 

Yes we are having few additional execution steps (like DB update/JMS etc ) in each service so we are having different VSMs.

 

Thanks

A feature that allowed regex to be used in setting the base path would be helpful to me as well!
