How to disable extra visit to portal server

Question

hi Experts,
I am using wcp11.1.1.8, in a customized page template with portal builder, I used an EL expression to generate link like this:
"http://localhost/webcenter/portal/Portal1/page1?_adf.ctrl-state=1dvjebskda_596"
I clicked this link, using httpwatch to monitor network traffic, found IE visited portal server twice: first visit is a "Get" method for ""http://localhost/webcenter/portal/Portal1/page1?_adf.ctrl-state=1dvjebskda_596"", result code is 200, the second visit is a "Post" method for "http://localhost/webcenter/faces/oracle/webcenter/page/scopedMD/s64679523_e5d0_454a_952a_55128e607e07/Page7.jspx?wc.contextURL=/spaces/Portal1&_adf.ctrl-state=1dvjebskda_596", result code is 200.
If I paste this url "http://localhost/webcenter/portal/Portal1/page1?_adf.ctrl-state=1dvjebskda_596" to ie addressing  field, and press return, httpwatch showed me there is no "second visit" for "/faces/oracle/webcenter/page/scopedMD/s64679523_e5d0_454a_952a_55128e607e07/Page7".
Seems the "second visit" is auto generated by portal framework, how to disable it?
Best regards

Hi.
Sorry about the delay, I was too busy and I only could do a small testing.
I was checking quickly how WebCenter Portal (formerly Spaces) works with links compared to Framework Portal.
The responsible of the "possible twice visit" is the following ViewHandler: oracle.webcenter.webcenterapp.internal.view.navigation.NavigationViewHandler in spaces-model.web.jar (method getPageTargetViewId, getActionURL and also isRedirectRequired).
First of all, try to check that you're Pages have the "Redirect" checkbox unchecked (or you're navigation-model links). In case of being checked it will be 2 Requests.
There are following behaviors:
Using <af:commandLink> just will navigate using PPR and doing a POST.
Using <af:goLink> using goLinkPrettyUrl there are many behavior:
Already wc.contextURL is present in the URL and then it will call just one GET.
If not is present, getActionURL it will add it in order to maintain the correctly the relationship Page - Space. It will generate you're behavior.
I'm trying to understand why sometimes just call one GET and why sometimes generate a GET,POST,GET behavior.
Anyway if it's urgent open a SR to Oracle.
I think that If you try to add to your goLinkPrettyUrl the wc.contextURL parameter it just should do a visit once time (one GET). Try it if you have free time .
I hope this information helps.
Regards.
