Using iFiles with iRules - Updating Problem

Hi,

I’ve run into an issue that I cannot seem to find an answer to, so, I’m hoping someone can point me into the right direction.

Basically, I have an iRule that checks if there’s at least 1 active member in my pool. If there’s not at least 1 active member in the pool, the iRule will put up a maintenance page; that maintenance page is an iFile called MaintPage (just a basic html page).

My problem is that if I make a change to the iFile, that update will not register/refresh and continue to use the old version. My workaround has been to edit to the iFile and then remove it from the list (Local Traffic>>iRules : iFile List>>MaintPage) and then add it back in order for it to update. Hope that makes sense…

Here is the iRule for reference:

when HTTP_REQUEST {
switch [HTTP::host] {
"sub.domain.com" {
if { [active_members my-pool] < 1 } {
HTTP::respond 200 content [ifile get MaintPage]
} else {
pool my-pool
}
}
}
}

Thanks again for looking,

Zac

    Thanks, I was able to figure this out.

    Before, I was using vi to edit the file in "/config/filestore/files_d/Common_d/ifile_d/MaintPage.html" and after I made the update, the page wouldn't reflect the update.

    Now, I go into tmsh and enter "edit sys file ifile MaintPage.html" and after I make the changes, the page is updated.

    Thanks!

    My problem is that if I make a change to the iFile, that update will not register/refresh and continue to use the old version.how did you modify the file?

    This is my testing.

     create text file
