Add basic authentication for specific page

you know event disable will disable the event on that connection, don't you? subsequent http requests on the connection will not trigger the irule.

Nitass, thanks for trying to help. My aim is for the authentication to kick in only if a specific page was requested. Do you have any suggestions on how to make this work?

I made a small correction at the first stage:

when HTTP_REQUEST {
if {not [string tolower [HTTP::uri]] contains "somepage.jsp"} {
    event disable all
return
}

My aim if for the following part to be executed only if the first part page was found

binary scan [ md5 [HTTP::password]] H* password
if { [class lookup "[HTTP::username]" authorized_users] equals $password } {
log local0. "User [HTTP::username] has been authorized to access virtual server [virtual name]"
} else {
if { [string length [HTTP::password]] != 0 } {
log local0. "User [HTTP::username] has been denied access to virtual server [virtual name]"
} 
HTTP::respond 401 WWW-Authenticate "Basic realm=\"Secured Area\""
}
} 

My aim is for the authentication to kick in only if a specific page was requested.

do you really need the event disable command? can you use only the return command (i.e. remove the event disable command)?

OK. tried to remove it.I am getting (same as before): "Error code: ERR_CONNECTION_RESET" no matter what URL I am trying to access.

When removing the iRule the site works as expected.

have you checked /var/log/ltm? was there any error?

I see the following error message. Does this means I can not use NOT statement with the URI value?

 - can't use non-numeric string as operand of "!"  while executing "if {not [string tolower [HTTP::uri]] contains "somepage.jsp"}
{      return }"

can you enclose it with parentheses?

e.g.

not ([string tolower [HTTP::uri]] contains "somepage.jsp")

Is this OK?

Hi Nitass,

Thank you, it worked!:

`when HTTP_REQUEST {
if {not ([string tolower [HTTP::uri]] contains "somepage.jsp")} {
return
}
binary scan [ md5 [HTTP::password]] H* password
if { [class lookup "[HTTP::username]" authorized_users] equals $password } {
log local0. "User [HTTP::username] has been authorized to access virtual server [virtual 
name]"

} else {
if { [string length [HTTP::password]] != 0 } {
log local0. "User [HTTP::username] has been denied access to virtual server [virtual name]"
} 
HTTP::respond 401 WWW-Authenticate "Basic realm=\"Secured Area\""
}
}`
