HTTP::collect¶
Description¶
Collects an amount of HTTP body data, optionally specified with the
length argument. When the system collects the specified amount of
data, it calls the Tcl event
HTTP_REQUEST_DATA or
HTTP_RESPONSE_DATA.
The collected data can be accessed via the
HTTP::payload command.
Note:
- This command cannot be called after any Tcl command that sends an HTTP response (e.g. redirect, HTTP::redirect, and HTTP::respond). A run-time error will result.
- If multiple iRules attached to the same virtual execute this command, the last collect wins, meaning the earlier one will be ignored. Having many HTTP::collect across multiple iRules is not a supported operation and should be avoided. The reason is that when performing actions with collected data (like HTTP::retry or HTTP::respond) it will implicitly cause the further operations against a collected data to break since it has been already released.
