Transfer file 30M+ with enabled ASM

Hello.

I have a ASM enabled SSL-site. I need to transfer files via HTTP PUT with size more than long_request_buffer_size (default 10M, maximum 30Mb).

I tried to use an iRule script to stop ASM processing but nothing happened, large files are not transfered.

What should I do?

Thank you.

when HTTP_REQUEST {
if {[HTTP::method] equals "PUT" } {
ASM::disable
log local0. "ASM disabled for upload directory for [IP::client_addr]."
} 
else {
ASM::enable SSSSSSSS
log local0. "ASM enabled. Current ASM policy is [ASM::policy]"
}
}
