HTTP::uri equality question

Hi jrok,

 

 

The switch statment is a literal string compare. Pretty much the same as "equals".

 

 

The "==" is an absolute comparison which is normally reserved for number value comparisons and in your case it has to convert the "/maintenance" to a string since it is not a number and then perform a string compare (extra work and less efficient).

 

 

I have no idea why you would be getting an SSL connection reset. I've never seen that problem before in a compare like this, but to answer your other question, yes, there are other comparisons that you can do within an if statement.

 

 

starts_with

 

ends_with

 

contains

 

equals

 

 

Hope this helps.

Hey thanks Michael.

 

 

I had re-purposed an older more complicated iRule for a new site and removed the switch and just made it an if. It took awhile to figure out what was causing the connection error but it was the if. If I put back the switch it works perfectly. We also thought the == might be the problem so we tried equals too.

 

 

Should this work?

 

if { [HTTP::uri] equals "/maintenance" }

 

 

We can certainly use the switch with only a single comparison but it seems like the if should work too.

Yes, that will work, but it's an absolute search.

 

 

So if somone went to http://www.website.com/maintenance/index.html or anything after "/maintenance" the iRule would not work.

 

 

I would suggest using "starts_with" so that it would basically be http://www.website.com/maintenance(anyting you could possibly put after it to qualify for this action).

 

 

Strange that you had to remove the switch statement. In a switch statement you have to enabe the "-glob" in order to use Wildcards to basically compensate for not having the starts_with or ends_with options.

 

 

switch -glob [ string tolower [HTTP::uri]] {

 

"*/maintenance" { action } <- Compensates for "starts_with"

 

"/maintenance*" { action } <- Compensates for "ends_with"

 

 

Hope this helps.
