NimbostratusMore Custom WAP Irules
I first want to thank everyone that has done WAP before. I liked the Irules I saw and got most of them to work in my test. However I have a problem some of the newer phones do not allow multiple redirects and I'm running into a crunch.
This is a sample of the code that my "WAP content" provider wants me to use to do the redirection based on the phone. This is not an irule of course but I have to find a way to make it an irule. My site went pure Ruby on Rails so I'm kinda in a bind.
The problem is they need me to point different phones to different "http://wap.vendor.com/partnergenericURL"
<% String accept = request.getHeader("accept");
if (accept != null) {
int i = accept.indexOf("wap");
int j = accept.indexOf("vnd.wap.xhtml+xml");
if (i > 0 || j > 0)
response.sendRedirect("http://wap.vendor.com/partnergenericURL");
else
//display partner homepage page normally
} else {
// display partner homepage page normally
}
%>
I forgot to add this. This is my current Irule based on the WAP irules I have found here on the site. What they are "saying" is that Nextel and some other vendor do not allow more then one redirect.

Thank you all for your help and input. I'm going to continue to search the forums
- For this code
<% String accept = request.getHeader("accept"); if (accept != null) { int i = accept.indexOf("wap"); int j = accept.indexOf("vnd.wap.xhtml+xml"); if (i > 0 || j > 0) response.sendRedirect("http://wap.vendor.com/partnergenericURL"); else //display partner homepage page normally } else { // display partner homepage page normally } %>
The equivalent iRule would bewhen HTTP_REQUEST { if { [HTTP::header exists "accept"] } { switch -glob [HTTP::header "accept"] { "*wap*" - "*vnd.wap.xhtml+xml*" { HTTP::redirect "http://wap.vendor.com/partnergenericURL" } } } }

Roger_Oliver_78Thank you
This is what I got now and it is working better... The problem seems to be that every phone vendor and version of phone has problems, as I change the order I fix one and break another. I will have to keep playing with it however your solution has helped me find a light in the darkness that is the iphone world.
Again thank you for the help.

}- It looks like you're closer...let's see if I can help a little.
You're going to want only one switch per header, otherwise you're going to run into issues, especially since you're using redirects and return statements. Try condensing these a bit, like:when HTTP_REQUEST { switch -glob [HTTP::header User-Agent] { "*hiptop*" - "*AvantGo*" - "*Danger*" { HTTP::redirect "http://wap.vendor.com/partnergenericURL-D" return } } switch -glob [HTTP::header Accept] { "*vnd.wap.xhtml+xml*" - "*vnd.rim.html*" { HTTP::redirect "http://wap.vendor.com/partnergenericURL-C" return } "*vnd.wap.html*" { HTTP::redirect "http://wap.vendor.com/partnergenericURL-B" return } "*text/vnd.wap.wml*" { HTTP::redirect "http://wap.vendor.com/partnergenericURL-A" return } } if { [matchclass [string tolower [HTTP::uri] ] starts_with $::ot_recover] > 0 } { pool OLD_WEB_POOL } else { pool WEB_POOL } }
That's a good first step in troubleshooting, anyway. If you still have problems, at least the logic will be a bit more condensed and you won't have to worry about the other switch statements not being evaluated.
HTH,
