Hi Mohamedabogamil , 

Use this irule : 

when HTTP_REQUEST {
if {[HTTP::uri] starts_with "/OA_HTML/"} {
HTTP::host [string map {":4443" ""}[HTTP::host]]
HTTP::uri [string map {"local" ""}[HTTP::uri]]

log local0. " the new URL >> [HTTP::host][HTTP::uri] "
}
}

Note : iRules consume CPU cycles , so keep your eyes in your system resourses for any spikes after applying this irule. 

This irule should meet your requirements and here below the output from /var/log/ltm file

[root@bigipA:Active:Standalone] config # tac /var/log/ltm |grep -i "rule"  
Nov 12 04:12:35 bigipA info tmm[16702]: Rule /Common/Replace <HTTP_REQUEST>:  the new URL >> 10.1.10.35/OA_HTML/APPSLogn.jsp 
[root@bigipA:Active:Standalone] config #


I hope you find this insightful 🙂

Mohamedabogamil , 

If you need to omit the removed parts in the URL from appearing in the browser, 
I believe you can use redirection and clone the same Virual server but with the https /443 port. 

here this editied irule : 

when HTTP_REQUEST {
if {[HTTP::uri] starts_with "/OA_HTML/"} {
HTTP::host [string map {":4443" ""}[HTTP::host]]
HTTP::uri [string map {"local" ""}[HTTP::uri]]
log local0. " the new URL >> [HTTP::host][HTTP::uri] "
HTTP::redirect "https://[HTTP::host][HTTP::uri]"
}
}
