NimbostratusNaging "command is not valid" by persist
Hello,
I try to create an iRule who set a persistence due to an GET-Request-String named "id=XXXXXXXX".
Here is the rule:
---
when HTTP_REQUEST {
set sess [findstr [string tolower [HTTP::uri]] "id=" 8 ";"]
if { $sess != "" } {
persist add uie $sess
pool http
} else {
pool http member 192.168.10.10:80
}
}
---
A rule with nearly the same works. But this one keeps barfing with the following error:
line 5: [command is not valid in current event context (HTTP_REQUEST)] [persist add uie $sess
What did I wrong on this one?
(OS: 9.4.7)
TIA,
bsdpruegelknabe

Have you tried "persist use $sess" instead.
I hope this helps

bsdpruegelknabeHello,
With persist uie "$sess" it works. (At least I don't get an error message.) Thanks for the hint.
So I don't need to add an persistence entry?
As result I need that all requests with eg. "id=1234" goes to Member1 and with "id=2345" goes to Member2 and so on... where the numbers are an alphanumeric String.

bsdpruegelknabe- The_BhattmanHi,
The only time you need "add" entry is when load balancing server is known. In this case you were using before that happened which caused the issue.
