Want http request limit !!

when HTTP_REQUEST {

 

set cur_time [clock seconds]

 

if { [HTTP::request_num] > 1 } {

 

if { $cur_time == $start_time } {

 

if { $reqs_sec > 3 } {

 

HTTP::respond 503 Retry-After 2

 

}

 

incr reqs_sec

 

return

 

}

 

}

 

set start_time $cur_time

 

set reqs_sec 0

 

}

In the example you've posted, taken from Unruley's posting in the thread mentioned, the reqs_sec variable is a variable that he's setting with the incr command. That command will increase the value of recs_sec by 1, and if the varible doesn't exist, it will initialize it and set it equal to 1.

 

 

You can read more about the incr command in the TCL docs, here: Click here

When I use this iRule, I can see error message.

 

 

when HTTP_REQUEST {

 

set cur_time [clock seconds]

 

if { [HTTP::request_num] > 1 } {

 

if { $cur_time == $start_time } {

 

if { $reqs_sec > 3 } {

 

HTTP::respond 503

 

Retry-After 120

 

}

 

incr reqs_sec

 

return

 

}

 

}

 

set start_time $cur_time

 

set reqs_sec 0

 

}

 

======================================

 

I don`t know what the error message is.

The error is stating that the HTTP::respond 503 command is not executing properly. Have you tried the HTTP::respond syntax from the above rule, or perhaps responding with different HTTP codes to see if that may solve the problem?

I already tried the HTTP::respond syntax from the above rule.

 

But it is same problems.

I need HTTP::respond 503 error message.

 

Please help us.

I've also run into an issue with 503 - seems it's not supported, or perhaps it needs a RetryAfter param. Didn't get a chance to check it out further, as 501 works just as well for our application and doesn't generate an error.

 

 

I'll also be posting a nice request rate limiting iRule to the codeshare later today or tomorrow... stay tuned.

Thank you deb!

 

Please, can I see your posting ?

I'm pretty sure this is the rule she's referring to:
