    You can apply the following iRule to your virtual server: The "/upload" is in the path of the file you are uploading. Note that ASM is disable when uploading and malicious files could be uploaded in this particular location without detection...

     

    ++++++++++++++++ when HTTP_REQUEST { if {[HTTP::uri] contains "/upload" } { ASM::disable log local0. "ASM disabled." } else { ASM::enable /Common/ log local0. "ASM enabled. Current ASM policy is [ASM::policy]" } } +++++++++++++++++++

The users with certain IPs will have ASM disabled only when they are trying to upload...
