[001] What's DigProxy's aim?
The aim of this service is to allow access from any workstation to the electronic resources acquired by the Library System, which are usually available only from the university intranet. By this system, when a request for an electronic resource is placed from outside the intranet, an authentication is required.
[002] Who is this service addressed to?
All Politecnico users, i.e. professors, researchers, students, staff, Ph.D. students and research assistants may use this service, if they are authorized. They can register by filling in a form; more information is in the policy.
[003] Can I use DigProxy to navigate anywhere? 
No, you can't. The websites reachable through DigProxy are only the ones listed in its configuration. It's not a common proxy (like squid). At the moment, DigProxy is set to access the remote resources listed in the pages electronic resources and trials.
[004] Why can't I access some of the resources of the digital library through DigProxy?
Some of the resources can be accessed by one user at a time, because their terms of sale don't allow multiple accesses. Thus, you can look up them just through some workstations located in the libraries which have bought them. The descriptions of the resources state clearly whether they are remote or local.
[005] I am an authorized user. How can I authenticate?
You just need to navigate through the links in the electronic resources list and, if you're connecting from outside the Politecnico intranet, you will be requested to authenticate yourself. The credentials you need to use are your institutional email address as username and the relative password. Students can use only their address in the form sXXXXXX@studenti.polito.it, other aliases are not accepted. All other users, on the contrary, must use only their address in the form name.surname@polito.it while aliases such as surname@polito.it or dXXXXXX@polito.it are not accepted. Anyway you must use the username notified in the confirmation email. If the authentication succeeds, you will be able to navigate through the relative websites as if you were connected to the intranet.
[006] Is my password safe in DigProxy?
DigProxy forces the connection for the authentication through the secure protocol (https), avoiding any security risk. After the authentication, your session will proceed through the usual protocol (http).
[007] Does DigProxy keep track of my traffic?
To avoid abuse and for statistical purposes, the amount of pages downloaded by any user is kept under control. No check is made on the content of the pages.
[008] I'm using one of the targets reachable through Digproxy, but some of the links therein are not accessible. Why?
Browsing the websites listed in the configuration of DigProxy, it is possible to run into links that lead to pages which require authentication. This usually happens clicking on links related to bibliographic citations. The cause could be one of the following:
The University is not subscribed to the requested resource. There is no solution, but to buy the resource itself.
The University is subscribed to the resource, but DigProxy is not configured correctly to allow the access. In this case you only need to notify the problem to bibli.digproxypolito.it
[009] Do I need to configure my browser to use DigProxy?
DigProxy needs to write a session cookie on your workstation, so cookies must be anabled, at least for the websites *.ezproxy.biblio.polito.it.
[010] I am an adjunct professor and I haven't an official e-mail account. How can I use DigProxy service?
DigProxy grants access to the resources from outside the intranet only after the authentication. To make it easier, the Library System has chosen to rely on the authentication system of the institutional email service, since EVERY student and employee, including external Professors, are allowed to have an account. If you don't have your address @polito.it, you can ask for it (look up the faq of email service).
[011] I'm registered, but I still can't use the service. When I try to access a resource a password is required. Why?
To use DigProxy service you need to reach the resources via the links present on the Library System website. On these pages links are modified so that navigation is forced through a proxy, which can recognize internal and external workstations. If you try to access the resources using direct links, the connection won't pass through DigProxy server and you won't be identified as an authorized user. Ex. direct link: http://www.edu.alinari.it/login/index.asp?languageID=... reachable from University intranet, but not from outside; filtered link: http://www.edu.alinari.it.ezproxy.biblio.polito.it/login/index.asp?languageID=... this link actually leads to a server of the Library System, which tests the origin of the request and, if necessary, requires identification, otherwise allows free navigation.
[012] I am a student. How can I use DigProxy service?
Students can register to Digproxy like the other users, by filling in this form. The registration will expire at the end of the student's career.
[013] I am a student, I used to be registered to DigProxy service in the past, but the registration is now expired. Since the new terms of use canceled any expiration, may I register to the service again?  
Yes, you may. You can request the registration again, through the usual form.
[014] I am part of Politecnico's staff. I had already registered when I was a PhD student, but now I can no longer access the resources. Why?  
In the Library System's database, PhD students are recorded under the ID provided by the Registrar's Office, while the employees (professors, researchers, technicians, etc.) under the ID provided by the Personnel Office. Thus, when a student gets his/her PhD and Politecnico hires him/her, a new ID is assigned. As a consequence, the registration request must be placed again.
[015] Do I need DigProxy service when I'm connected to the University intranet through the VPN service (provided by AreaIT, ex CeSIT)?  
VPN service, provided by AreaIT, uses a secure channel to connect to computers inside the University intranet. It has no effect on external computer using it. This means that when a user tries to access an electronic resource, his/her workstation introduces itself to the Publisher's server with the IP address assigned by his/her Internet provider. Thus, the user needs DigProxy to access the resource. By the way, if you're connected to the University intranet through VPN, you can set your browser to use the University proxy (proxy.polito.it, port 8080, how-tos for MS-Explorer and Firefox). In this case you don't need DigProxy to access the resource.
[016] How can I send my feedback (more information, explanations, comments...)?  
For further information, or to notify problems or any other feedback on Digproxy, send an email to bibli.digproxy@polito.it
