Caching Http Requests

[vincentmuthomi]

Caching does not seem to work

My setup

• Chrome -> not chromium
• Persistent context
• A http proxy server
• No page.route or context.route. Saw that there was an issue with this in caching, but I do not implement it.

The Issue

When using an ordinary browser, I get 200 OK (from memory cache) and the x-cache: RefreshHit from cloudfront
On the patchright controlled environment, I get 200 OK but the x-cache header is non -existent in most staticly served files.

The result, the page takes forever to reload

Diagnosis

• Tried to run the proxy server across a normal browser without playwright and the result was as expected, caching was working fine hence ruling out the effects of the proxy server

• Tried to change a couple of default injected args when running chrome, nothing worked

Below is the setup code I used, also to add, I was testing the ignore-default-args one by one. The script below showcases all the arguments I tested.

 async with async_playwright() as p:        
                
                proxyConfig = self.proxyConfig
                host = proxyConfig.host if proxyConfig else "no proxy"
                port = proxyConfig.port if proxyConfig else "no proxy"
                context = await p.chromium.launch_persistent_context(
                    user_data_dir="chrome-data",
                headless=False,
                args=["--no-sandbox",
                    '--disable-blink-features=AutomationControlled',
                        "--disk-cache-size=104857600", 
                        "--memory-cache-size=52428800",  
                ],
                ignore_default_args=[
    "--disable-back-forward-cache",
    "--disable-field-trial-config",
    "--disable-background-networking",
    "--disable-features=AvoidUnnecessaryBeforeUnloadCheckSync,BoundaryEventDispatchTracksNodeRemoval,DestroyProfileOnBrowserClose,DialMediaRouteProvider,GlobalMediaControls,HttpsUpgrades,LensOverlay,MediaRouter,PaintHolding,ThirdPartyStoragePartitioning,Translate,AutoDeElevate,RenderDocument,OptimizationHints",
],
                channel="chrome",
                #executable_path=chrome_source(),
                no_viewport=True,
                accept_downloads=True,
                proxy={"server": f"http://{proxyConfig.host}:{proxyConfig.port}",
                       "username":proxyConfig.username,
                       "password":proxyConfig.password
                       } if proxyConfig else None
                )

My thought process

Something in either playwright or patchright may be causing the problem. Any assistance will be appreciated
