Can we Insert HTTP Header using HTTP Profile for a dynamic tranaction id generation

Hi Kalyan,

 

 

You can use iRule syntax in the HTTP profile header to insert field, but I think it needs to be on a single line:

 

 

TRANSACTID [incr [expr { int(10000000 * rand()) }]]

I didn't test that first. It results in a runtime error as incr expects a variable--not a number:

 

 

expr { int(10000000 * rand()) }

 

4888651

 

 

incr 1

 

can't read "1": no such variable

 

 

Can you try this instead:

 

 

[expr { int(10000000 * rand()) }]

 

 

This will generate a random number for each HTTP request. It will not increment a past value, so the ID numbers won't be sequential. If you wanted to store the past value in a global variable, you'd need to use an iRule.
